I had when naming a new workstation the same as the one I am replacing on the domain was that I noticed the new pc with that same computer name as the previous pc was still trying to use the IP address that was assigned to the workstation before by dhcp, so the new workstation was not showing it assigned an IP address. I would try pinging the computer name but there was no reply because it was still showing the ip address of the computer disconnected that had the same name.
adding/removing/re-adding a workstation to a domain and Active Directory. We use DHCP at work for our addressing scheme. The problem I had when naming a new workstation the same as the one I am replacing on the domain was that I noticed the new pc with that same computer name as the previous pc was still trying to use the IP address that was assigned to the workstation before by dhcp, so the new workstation was not showing it assigned an IP address.

- remove the faulty workstation from the domain to workgroup, then restart
- then from Active Directory do I need to reset the Computer name
- then do a ipconfig /release on faulty workstation that has been removed from the domain to release the leased ip address in dhcp
- then disconnect the faulty PC and connect the PC I am using to replace the previous PC
- Name this workstation the same as the one I just disconnected and removed from the domain
I am configuring a few new computers for an office and I would like to rename the printers we have here. There are 2 printers at the front desk that have confusing combinations of numbers and letters for names and I would like to name them something like "front desk color" or "front desk b&w". These computers are connected to a network and accessable from 10+ computers.
We need to rename our 4404 Wireless LAN Controllers. Would like to know if renaming via the GUI (change name in the Controller / General tab and then Apply) will cause the WLC to reload. Also wondering about the best way to push the name change to the APs (High Availability) - we are not using WCS.
I have a N750Db router along with a Dual-band wireless range extender. It works great, but it created two new networks with "_xt" at the end of the SSID to denote the extended networks. This means I have to disconnect/reconnect to the base/extended networks as I move around my house. If I were to rename the extended networks to have the same SSID as the base networks, would that allow me to walk around my place without having to connect to the extended network, or will it create some sort of conflict or error?
I have purchased a subnet of 8 private IP addresses from my ISP. 109.x.x.128/29.The ISP has placed a juniper router within our data centre which is routing purely from 109.x.x.206/30 to 109.x.x.128/29 with the ip of fa0/1 set to .129.
I have linked a cisco 5505 to fa0/1 of the juniper from fa0/0 and configured its IP to .130. I have configured NAT to translate our client pool 192.168.16.x /24 address' to the internet.
Is it possible for the 5505 to route / map my remaing private IP addresses through its external port? I have tried creating a seperate VLAN for a DMZ for our servers to sit within but am returned with a subnetting error as VLAN for my external port is all ready configured within the same subnet.
You are appointed as a system administrator for a large company which has its own computer intranet hosting 150 workstations and around the same number of users. Write few points explaining the roles you would expect to take on as part of your new employment in terms.
I have an office server set up to about 10 computers. We hired 4 new people and had to set up their computers on our network. Set up was easy and quick as usual. But when I was done, the other computer users, and even the new ones were complaining about not being able to access the DEFCON5 (name of our server) folder to get what they needed.
Basically the only workstations that show up when I click Network are the computers I added the other day, and the computer that is used more than any other computer (the CEO's). We can still access the files by typing the location as \DEFCON5****** and find what we need. But not everyone at my office is computer savy (no body is) and I would like to not have to keep running around and showing everyone this.
At the company I work for, there are a few "network drives" to which employees are given access so that any mutual file stored thereon may be shared between and edited on demand. Not the best model, I know.Went to the server room a few minutes ago and found that "network drives," (P:), (L:) and (M:) seem to be invisible. Back at my workstation, I opened My Computer and saw all three on my screen.

We are having several workstations that are momentarily losing connection to our Windows Server 2008 machine that hosts their Documents etc.It seems like a momentary disconnection and not everyone has complained although I'm guessing that unless you are trying to locate a file etc at that moment you might not notice.Here is the error message I see in the event logs on the server:
-Source: srv -EventID: 2012 -Level: Warning
While transmitting or receiving data, the server encountered a network error. Occassional errors are expected, but large amounts of these indicate a possible error in your network configuration. The error status code is contained within the returned data (formatted as Words) and may point you towards the problem.So, where would you guys start with something like this? Either my HP Procurve 1800-24G doesn't have much in the way of error logs, or I don't know where to look.Would you start with changing port on the switch, changing network cable or do you think it's more likely to be something on the server itself?
I have an ASA5505 where vlan1 (inside) and all associated ports (e0/1 - e0/7) are down. Workstations on vlan 1 are online and working. Vlan2 (outside) is up and running normally. I tried to shut/no shut on the vlan. I also rebooted the firewall. No change. Why vlan1 is down?? I've attached some config info and some troubleshooting.
Recommend a low-cost Cisco-branded router/firewall for a clinic with perhaps 10 user workstations? We're looking for something that will support attaching a static VPN to a data center.
Currently we're using a Cisco RV082 in our office, but there might be a device which is more appropriate for the next office we connect to the data center. On the data center side we're using a Juniper SSG5.
Under Service in Win NT 2008 server, how can I remove the auto-shut down task schedule for all students' computers in the classrooms. It always popup a message box at 5:30pm - "auto shutdown" in all workstations (win xp). How to remove that from "service" and not affecting the server to shutdown? Click where to disable/stop it?
I have a WRV210 router setup with WPA personal-AES encryption...SSID is turned on. The issue is that workstations lose connectivity to the internet and to a mapped network drive on the server. When this happens I find that the wireless status shows "connected", along with excellent signal strength. It never happens when logging on, just after so many minutes. The simple remedy is to repair wireless connection but we would like to not have to resort to this behavior every day. Further, I found that within the repair connection sequence that deleting the address resolution protocol table, brings the internet and the ability to access a mapped network drive back. I even used a program called arpfreeze to assign static ip's to the arp table and I still had to repair wireless connection. It does not matter where the workstations are placed, whether sitting 50 feet away or 5 feet from the router, the workstations lose the ability to access internet and mapped drive while showing "connected" and excellent signal strength. Otherwise, we are looking at running ethernet cables through the building (Not easy).
I'm completely illiterate with Cisco appliances but I'm taking care of an ASA 5505 that is configured as a firewall and it has been working for the last years. All of the sudden we are experiencing intermittent connection problems from the workstations. You can be browsing the internet and suddently you'll get a server not found error but you refresh it and it works. This is also intermittent, out no apparent reason it will start working normally again.
I am seeing a bunch of errors like this in the logs:
We have a number of sites running Cisco 881 routers. A few of the sites are connected by IPSec VPN tunnels that have been configured using Cisco CCP without any issues until now. On one location I can ping from a workstations on Site1 to Site2, however I cannot ping from the same workstation on Site2 back to Site1.
Here is a strange behavior. If I have a continuous ping going from Site1 - Site2 and then start a continuous ping from Site2 - Site1 then I get a response until I stop the ping from Site1 - Site2. Site 1 has approximately 5 successful tunnels with absolutely no issues.
Site 2 Cisco 881 running Version 15.2(3)T1 crypto isakmp policy 2encr 3desgroup 2crypto isakmp key ThePreShareKey address TTT.UUU.VVV.224 [code].....
For additional troubleshooting I established a VPN tunnel from Site2 to our office Site3 with no issues at all. Site3 happens to be one of the VPN tunnels that connects to Site1 with no issues. I have seen a number of articles on this on the net and gone through the troubleshooting steps of an article such as [URL]. The tunnel is confirmed as up when I have done all my troubleshooting.
We have a network of approximately 20 computers, network printers, and one Windows 2003 Server (used simply as a file server). I have an issue with two specific Windows 7 Pro workstations that just will not logon. The username and password details we're using are correct, but the server rejects them. I can logon using the same account from any other Windows 7 Pro workstation, or Windows XP station, so I know the issue is specific to the two workstations communicating with the server.
Both afftected stations show Logon attempted by: MICROSOFT_AUTHENTICATION_PACKAGE_1_0 error 0xC000006A which all searches on Google point towards incorrect login credentials, however I've tried plenty of perfectly valid login credentials and they don't work either.I've tried checking that the 128bit option on the Windows 7 machines is disabled in file sharing etc.
I have a Active Directory user that cannot log onto any computer that's on my organizational domain. The error is "You cannot log on because the logon method you are using is not allowed on this computer"
I cannot join domain it saying that "Computer name changes", A domain controller for the domain MyDomain could not be contacted.”. We have domain and workgroup, Actually first its already joined the domain, but I want to map the sharedrive inside the workgroup but I cannot map. Then I change to join workgroup. After I boot up I cannot log in with that user, I log in with administrator and the user is dissappear in the "User Account", but the profile inside document and setting still left surprise. I don't know why Now I create one more user, it can map to share drive also share folder. also can see all other network computer. But only left one is I cannot join the domain. I need this one because of we don't let our user using as administrator account. Before I testing this one I should backup, but now the time
Have a school which is split into 2 domains (and 2 different subnets). A logged in windows domain user from domain A needs to access a windows share on domain B. So I made a bat file on the pc in domain A to map a drive to the share on domain B, using the net use command but specifying login credentials of a domain user from domain B.The pc on domain A has it's hosts file edited so it can access the server on domain B which the share is on, ping and everything to this server works fine.I created a user in domain B with the corresponding login details as in the batch file, same un and pwd, it didn't work. If I specify the un and pwd in the batch file as the domain admin account on domain B, it works fine everytime. I'm pretty sure it's not a premissions thing as I have given the inital user that I specified in the batch file full control to the share permissions and security permissions on the share in question, it still wouldn't work.
All I can think of, but can't put into good technical words, is that this user I am specifying in the batch file not only needs to have access to the share itself but has to enter the other domain as well, would there be some protocol or something in which it does not have permissions to use effictively but the domain admin clearly does as it works fine for domain admin?
how do I pass from domain server , my network in our compant have ISA server and they close some website like face book , how can I pass over ISA server and use my websites?
What the most cost and time effective way to have an ip request return with another ip address from outside the WAN of the router.Specifically want to have an application request for example 192.168.1.121 and have 173.194.43.41 respond and communicate with the application instead. To make it a bit more interesting I'd like actually to set a table or config file to point to a domain name (url) which gets resolved as an ip address. (Port independent)To get a better understanding:one example might be typing in 192.168.1.121 in a browser and googles search engine comes up on the browser.another example might be typing in 192.168.1.121 in an ftp client and it hooks to an ftp server on the other side of the world which resolves to [URL]. I was looking at openwrt and tomato a little but I don't think I have such a complete grasp on how to do it in general. Being that it seems they are 2 different layers of the network model, I was told it can't be done but I don't know if I can believe that yet. Either by third party software or reprogramming the router or adding another device to the network.
In my office we are using two networks , one is 16.x.x.x and another on is 15.x.x.x . 16.x.x.x having the domain controller. 15.x.x.x is only connected with Workgroup. my question is it possible to add 15.x.x.x network system into 16.x.x.x network . I tried to add but it gave error message "Domain Controller can not be contacted". Generally we cant add it into the domain i know that. is there anyway to connect the 15.x.x.x systems into 16.x.x.x domain using router in the network.
i need to know when a computer shutdown. Is a windows xp. Is in another domain. I cant use VPN.somebody knows a software that alert me (example: by email)?
Description: Windows cannot obtain the domain controller name for your computer network. The specified domain either does not exist or could not be contacted. Group Policy processing aborted.
Dad's work laptop (XP) will no longer connect to any wifi at all. I removed the Intel PRO/set wireless utility so it would default to windows, enabled the Wireless Zero Config. It will acknowledge the network, attempt to get an IP address from the network for 1 minute, then it rotates down to the next network SSID in queue (I have 3 SSID's in our house). When it reaches the end, it just goes back to the "Windows is not connected to any wireless networks" message.
i configured a network domain out of which i connected several machines to a single user via 8 port switch. earlier the machine was working. now a days when i log on to server through user it allows me to log on. i am having two problem. i am no longer able to see the entire network on server. when i try to connect to server, the user machine asks user name and password which is quite routine. when i provide user name and password it gives the message that "logon unsuccessful the username and password are the same which you entered at user logon" when enter the user name and password of server it allows me to go inside. after rebooting the problem persists.
i am finding an ip address which is some hardware laptop or something that has got that ip from our doimain network while connected to our network. I dont know who it is and what it is and i always use Advanced Ip scanner and shut down any pcs manually with it and search for illegal hardwares connected to our lan but thisone is unable to be turned off it says unsuccessfull.Is there any software that allows me to kick out hardwares from our domain network?
I use TP link-150M wireless Lite N router .Model no :TL-WR740N.I use this route to connect WAN and the computer connect to the LAN port for the router.I use DHCP to allocate the IP address from router in below case.I can browse and ping url...But I cannot ping/browse url...[code]
I do not have wireless internet access and I get the message "There may be a problem with your Domain Name Server (DNS) configuration" when I try to diagnose the problem.I am on the internet by bypassing the router and having a wired connection from the modem to the computer right now. The problem started when I tried to get a second computer to work with the wireless connection (so with the computer I'm on right now, wireless worked a few days ago). [code]
