Mapped Network Drive Fails At Random?
Mar 18, 2011
I am having an issue with 3 xp pc's in my network loosing connectivity to the file server. There are 4 network drives mapped to a win 2k3 server, when the user logs in everything is fine, after a while the network drives become unreachable and gives the following error - An error accrued while reconnecting (drive letter) to \servershare Microsoft windows network: The local device is already in use The connection has not been restarted” This happens from any user on only 3 boxes. The rest of the network is fine. These 3 are networked via a switch, I swapped that out for another hoping that might fix it, but nothing.
The other odd thing is the same time that the network drives error out it seems that DNS stops resolving anything outside my network. I can still ping the router and other pcs on the LAN but DNS fails to resolve any names for IE, and nothing outside the LAN can be pinged, no Google, no 8.8.8.8. How ever restarting fixes the issue for a short while. There have been no network changes and all systems are fully up to date as far as patches go. I was thinking it's got to be a ether a DNS issue (the file server is also the Active Directory Domain controller) or something in to do with the router/fire wall we use (it's a Cisco ASA 5005).

We have 4 computers that all run new versions of Windows 7. Each have been connected to a Mapped Network Drive and they all connect fine to the network. Dragging files throughout windows works fine. When we try to attach a file from the network in the browser (as in a GMail message) or upload a file with FTP it disconnects us from the network and from the Internet.This only happens with 2 of the 4 computer.

i have a user running Windows xp pro, the problem is one of his network drives does not re-connect at logon, all the other drives re-connect but for some reason this one does not, the network drive is on a windows server and does not require different logon credentials than his windows logon.

I have a windows 7 desktop with an SSD and regular mechanical hard drive where I keep my data. I also have a laptop with a small SSD as well. I wanted to keep the laptop free of non-critical data so I decided to setup a file share between my desktop (Windows 7 home prem) and my laptop (Windows 7 pro). I was able share the files and navigate to my desktop through my laptop. I successfully mapped the folder as a network drive and all was well. Then I rebooted and I was disconnected from it, it remembered that it was there but I needed to manually connect to it and I needed to provide my login credentials. There is no password just a username.
What is causing this and is there a way to get around this? Also is there a way to set a timeout because if my desktop is not on and I want to use my laptop, the boot times are much longer compared to when I don't have the mapped network drive on my laptop at all.

I got a strange incident happening to my work computer. Whenever i step away from my desk and come back only to find Icons of files mapped to other network drives other than my local drive have disappeared from desktop. I have to restart my computer to get these back. It only happens when i have walked away from my PC and I have verified that no one has sat at my desk to use my computer while I'm away. The other PC are also networked to the same servers as mine and theirs are not affected at all.

I have a Gaming Computer, with a 2x2TB RAID-1 setup, which I use to store .iso files ripped off my game's / movie's disks..Most of the time I'm on my laptop, I have set up a Network Drive to this RAID-1 setup, but when I try to transfer files from the Gaming Computer to my laptop via a network connection, either by wireless G, Ethernet 100mbps, or Ethernet 1gbps, my files get corrupted, this usually happens to larger files e.g over 1GB..But when I transfer the same files to my external hard-drive the files work properly....My computers is networked by a TP-Link 340G....

We are running about 75 computers in a network. We have a server here where all the clients have a shared folder that we map for them, but as soon as they restart their laptop, the map drive disappears. We are running a script that we tested on a network where the laptops were linked with a cable, but as soon as you switch over to wireless it disappears.

I have an HP Pavilion dv7 laptop running Windows 7 (64bit) SP1. Recently, my computer was attacked by some really nasty malicious software. Nasty enough that it not only got past my security software, it permanently disabled it.I was still unable to repair/replace my security software. Finally, the support tech just gave up on me, and I ended up utilizing the restore feature provided by HP to restore my laptop, supposedly to factory condition. After the restore, everything works great except for my mapped drive.

I have a desktop and a laptop. I'm trying to share my external HD from my desktop, to my laptop.What I did was gave the local administrators group full share permissions to the drive, and of course the local administrators group also has full NTFS permission.That being said, I went to my laptop and did a Code:net use X: \mydesktopexternal /user:mydesktopuser PasswordExternal is the share name for the external HD on my desktop. The command worked successfully, however, I am still getting Access Denied when trying to get inside of this mapped drive.How and why does the command map the drive properly, using those credentials, but there's no access when trying to navigate to it? It works if I give Everyone full share permission, but I don't want anyone to just connect to it. Use password protection file sharing is enabled, but of course with "Everyone" given permission, that won't apply (at least to my knowledge).

I have a domain with a domain controller Server 2003. I have a backup dc running an application with server 2008. The shared folder I am trying to access is on an nt server 2000. We have had a mapped drive "I:" and have used it for years. Our copier also scans to a shared folder on the server 2000 machine. All of the desktop systems are xp sp3 with one W7 machine. A couple of weeks ago when user attempted to access the shared/mapped drive, an error would occur that "the drive was in use and they could not be logged on". Sometimes the error would say "you don't have permission to access the drive." Mind you no settings have been changed on the network. When either of these errors would occur it would occur for everyone but if I rebooted the server everyone could connect again. The same errors would occur the next day or 6 - 8 hour later. Now the error has occured "Drive is already in use and you cannot be logged in" (I have tried drive Z as well the drive is not in use) and restarting the serever no longer works. No one can access the shared drive. I have unmapped the drive on my system and have attempted to reconnect, I enter the path and check reconnect at logon and it asks for a password. I enter the administrator password (which is what I always used) and it just pops right back up asking for a password as if I entered nothing. I can ping the server with the shared folder and even logon remotely so I know it is not a physical disconnect. I am not sure what changed and have followed many suggestions found to no avail. We cannot access the shares or scan.

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

I have several computers on a network hooked to a server. All of these computers are running XP and have are mapped to a drive on my server. The problem is, once in a while the mapped drive will suddenly not be there. I can manually remap them and sometimes I have to remap 2 or 3 times before it keeps.

I have two Windows 7 Ultimate computers and around 10 Windows XP (Home and Professional, SP2 and SP3) computers trying to connect to it. It's just a LAN (no internet access).I have set all of the password-protected sharing off on the Win 7 systems. I have tried opening up ALL of the permissions and such (since security is not really an issue).When I try to map the network drive, it won't let me merely connect to it. So, I have to click map network drive on the XP computer and hit "login with other credentials" and enter the username/pass for the user account on the Win 7 machine (we'll say Bob for user and Smith for password for the sake of example). It will mount the share (which is actually the C: root of the drive) just fine.
The only problem is the moment you restart the Windows XP system, it will lose the connection. My fix for it was to create a .bat file that contained the following: [code] I put it in the Progam FilesStartup folder to run upon boot. For the most part, it seems to work after a fashion. Some of the computers, though, will drop the connection to the two Windows 7 systems and need to be rebooted 1-2 times before they get it back again. Even clicking the .bat file manually will have the same result (you will have to reboot) if it drops the connection while you're using it. Plus, sometimes it doesn't map the drive correctly (I assume because the batch file is running before the connection has a chance to initialize on the LAN).I've also tried adding an "Everybody" user to the permissions on the Win 7 systems with full access, but it only seemed to cause problems with the existing connections.It might also be prudent to mention that both the Windows 7 and Windows XP systems are all 32 bit. I've also disabled the firewalls on the two Windows 7 systems. Neither of them have any antivirus or security software installed.

We are having some issues between our (2) Windows 2003 Storage servers and Windows 7 client machines. The issue that is occuring is that the users indicate they temporarily loose network connection to their mapped drives on these servers. This may happen several times a day. The regional manager wants to say it's a network issue but I believe it's something b/t the server and workstation.I like to know if there are some additional parameters, debugging or configuration that might be recommended to perform on our (4) Cisco 3750G-48port POE switches (stacked) that would determine that it's not a network issue. I do not see any errors or collisions on the ports that the servers are connected nor am I seeing much of anything wrong with the user ports. There are only 3 vlans at this office, vlan 30=users, vlan 20=servers, vlan 40=mgmt.

I've been having some issues with my network connectivity for a while now, and I haven't been able to figure out what the problem is. I run a wired connection to an Ethernet port in the wall of my university dorm. I have verified that it is not a global network issue or an ISP issue; this problem only happens on my PC.My network connection drops/disconnects randomly throughout the day. When I say disconnect/drop, I mean that all attempts to ping or access the internet fail. A few minutes pass before the Network and Sharing center task tray icon shows a warning sign saying that my computer could not connect to the internet.This is temporarily fixed by doing an ipconfig /release and ipconfig /renew, but I have to execute these two commands about 2-3 times a day on average.
There is no exact interval between the disconnects, nor does it happen when I am running particular programs. The disconnect happens regardless of what I am doing at the moment (gaming, browsing the internet, leaving the computer idle).A month back, I installed some Windows Updates and suddenly my internet connection was almost completely broken. I was experiencing the same issue, but much more frequently. My internet would die within 10 seconds of executing any download, but Windows wouldn't recognize that something was wrong. At first I thought the ZoneAlarm, Avast!, or the SafeConnect (as required by my university) services were causing trouble but uninstalling/disabling these services did not fix the problem.I also tried reverting to my default ethernet drivers, which did nothing. I uninstalled and reinstalled multiple versions of my drivers to no avail.However, the internet worked just fine in Safe Mode with Networking, so I cross-referenced the processes/services running in Safe Mode w/ Networking against my normal startup, guessing something else was at play.After some poking around, I discovered that disabling the Server and Browser services permanently fixed the issue of instant connection death. But the initial problem I described still remains;random, less frequent internet connection drops.

At first it seemed to happen everyday at the same time, but now seems completely random (happening twice a day somedays). At some part during the day while the user is busy with this system it drops the network connection. The ONLY way to get it back is by restarting via the reset button. Shutdown or even logoff just hangs. Nothing regarding that card will work or respond, you can not even disable and re-enable. I can however get the wireless to work without restarting. I've done everything I could possible think of including format and re-installing Windows. Something new I've noticed is that the user always has MS Access (in runtime mode) running while network goes down and then you can not end that process.

I have a mix of devices that all access the internet via a Deutches Telkom Speedport W 723v my windows devices, HTC phone and even the iPad 2 never have a problem, but my Macbook Pro (Unibody Late 2008 model) and my iMac (Probably 2007 / 2008) keep having a problem with the network dropping out. To fix it I have to switch off Airport and switch it back on again and it re-connects straight away.The Mac OSX software albeit now rather dated on both devices (The Macbook is 10.5.8) is kept up to date using Software Update.The problem amy also now be affecting my APPLE TV2 it never had a problem before but now I cannot connect to iTunes on my Macbook using Home Sharing it just does not want to connect!!!I did try before going into the Speedport and changing channels from AUTO to channel 1 but that did not resolve it. I am going to do it again and try a different channel but logging onto the Speedport is an absolute pain, I can only login using my Macbook Pro when it is booted into Windows XP and on Ethernet as we had all sorts of problems setting it up and could only do it using IE not SAFARI and now the Speedport login only recognises 1 x PC for logging in, if you try a different device it throws a wobbly and locks up!

I have been having intermittent wireless trouble. This includes Ping spiking, Wireless network drop-outs (The network stop appearing on available network list) and packet loss. This is all completely random (though very common) and is frustrating to say the least. As far as I know, the problem is not nearly as bad on other devices in the house , so I suspect that my network card has become shoddy. I have tried updating,removing,and re-installing network drivers to no avail. I have also used cmd and I have pinged 192.168.1.254, which shows random ping spikes, and some packet loss as well.

My router keeps crashing like it is restarting. it turns off then all the lights are beginning to turn un again after some time it repeats again and again....Last thing they did was turning down the internet speed for our Network. It worked in some time but then it begun crashing again...Then they said it was the cable in the road that could not take all the data stream... And something about and Bit error?I just dont belive the cable in the road thing because our neighbour are running 10 M/bits without a single error anytime... I am not an expert but i've found out that we are running a Sagembox or something like that. The hardware version (if that is important) is: 3DK04-02 Everybody in the house is running Win7 SP.1. If you need any more information then i will try to find them.

I keep getting random moderate Nat sometimes, other times its opened. I have made a static Ip and port forwarded 4 ports that xbox uses. 88 udp..3074 both...53 both...80 tcp... Now when i test my connection on the xbox dashboard a message will come up saying make sure my UpNp is enabled, which it is and it tells me to make sure port 3074 is enabled which it is. I have restarted both my modem and router multiple times to try and fix this.
I have a linksys cisco e4200 and I recently updated its firmware which i thought would possibly fix the problem.I have talked to linksys but no luck.I have talked to my internet Cox Communication but they tell me its the router and i believe it is because when i directly connect my xbox to the modem i never get the moderate Nat. I have also talked to Norton about my virus protection because I thought maybe it was blocking some ports, but they disabled it and I still get the message.

I noticed a TON of random devices showing up in my Network within Windows 7. When I say a ton, I mean 739! I am not computer illiterate, but definitely not a pro. My router is WEP password protected, so I'm not sure on earth is going on here. I thought maybe I had a torrent program open that could be affecting this somehow, but I don't..

I have this laptop with a built-in Intel Centrino Advanced-N + Wimax 6250 adapter to connect to WiMAX.Right now I have a WiMAX connection at home with a simple gateway. So what I want to do right now is trying to connect to this network using my built-in adapter.I'm facing right now is that the driver of the adapter only searchs for a certain provider from the US (Clear). I'd like to subscribe to their service but I live in Argentina so that's not a valid option. So my question is if you know of a custom driver or some other way to search for my local wimax network.

Wired PC randomly disconnects from network at random intervals each dayoday it has done so 3 times. The only way I have found to get it working again is to reset the router which can be inconvenient. When it disconnects all wireless devices continue to work and I have no issues like this with my wired consolesI switched to using a static IP address, since having an automatic one gave me the same results [i have since switched back to automatic]Be happy for any suggestions on how to sort this. I am using W7 OS and I'm using an Orange router. I don't know if its relevant, but when I go to reset my router I have noticed that the download light on my router is flashing like crazy when my PC has disconnected.

We have a bunch of computers(70 aprox) connected to a domain. Since couple weeks ago very strange issues started occuring, internet and network access(path to network share is lost) would come up at random times and on different machines and would last for about 10-20 seconds it would re-connect again.All the computers are using private addresses.Most machines are windows 7, some are xp.Using Windows server 2003 as dc.Since the occurance is so random it's very hard to pin point the cause.

This is also happening on more ports ie 20-printer, 13-Cisco Wireless Access Point, 24 File Server etc., which I don't know what is going on. With my research, it said something about spanning protocol. Is this possible to disabled?
The other cisco switch where desktop are also connected doesn't have this error.
My firmware is 1.1.0.73

I just built a new computer running Windows 7 with an Intel 82579V Gigabit on the motherboard. Since last night while playing an online game, I have occasionally noticed sudden network failures where I either time out of my game or severely lag for 10 seconds before the game catches up.
My other network hardware and setup remains unchanged during this build.I have never had issues with my internet connectivity from my ISP.
The problem is not consistent and I'm not sure how to repeat it. I was playing my online game for several hours and then suddenly started having problems every 5 minutes with disconnecting.I can watch the network utilization in the Windows Task manager drop suddenly and then spike back when I reconnect to the game. Similar visual seen on the Tomato software on my router.
So far I've grabbed the latest drivers for the network chip from my motherboard manufacturer's website and turned off Teredo. I also made sure no power saving features were enabled on the network chip in the device manager.

I'm trying to see if I can fix my friend's NAS which apparently has some pretty important data on it that wasn't saved anywhere else. They actually had the Geeksquad look at it and they've come to the same conclusion I have so far, but I figured I would ask the internet before I gave the thing back to them and said Geeksquad was right.
Anyways, they have this 5 drive RAIDed NAS which apparently just stopped showing up on their network. I borrowed it from them to see if I could figure it out. It turns on just fine and my router assigns it an IP address, but the IP address just takes me to a blank LaCie dashboard screen. It's weird because it's clearly running it's web server because it's just a gray background with an empty white box and "(c) LaCie 2010" at the bottom. No content at all.
Additionally, I tried installing the LaCie Network Assistant on my home computer and it says it cannot find any network disks. I've tried the "wake up a device" where I enter the mac address, but that doesn't do anything.
All the lights are solid blue on the front and over all the drives so it doesn't appear a drive has failed or something. Even so, that wouldn't really explain the blank dashboard right?

The problems looks like this: I'm able to browse the web without any problems until at random points of time - might be 2 hours after I turn on my PC or 5 or even half an hour the port 80 gets blocked - actually more like it hangs it self. As whatever I try to open i get "waiting for response" going and going. It's not even returning "page not found" error or anything. To top everything all other ports work fine - i can use https, ping run tracert - no problem there.
I've spend two days looking for some answer on the web but came up empty. I've scanned for malicious software with ad-awar and malwarebyte anit-malware - nothing came up. After restart of the pc everything comes back to normal but its frustrating needing to do that every now and then.
My home network looks like this: I have some broadband modem that is connected to local wifi TP-LINK router (Model No. TL-WR340G/TL-WR340GD). There are four devices using this connection - two pc's (laptops), android phone and android tablet.
