Other machines on my network can't seem to be able to see my machine, but i can ping them all. It can't be anything to do with the authentication because i have just reformatted my machine and re-added my machine to the AD.
View 1 RepliesI am having a weird issue with my Cisco 7200 router. From the router i am able to ping and reach out to the internet but from the client i am able to reach out to the internet but unable to ping I am not sure where is the issue but when i traceroute to it my packets are dropped at my routers interface. All my pings from the client time out. I checked the Access list to make sure ICMP is not blocked. Following is my running conf
ip audit notify log
ip audit po max-events 100
ip ssh break-string ~
ipv6 unicast-routing

We have been using the VPN client for a very long time. Our most current VPN setup is using an ASA 5510, without split tunneling. We tunnel all traffic. We are using IPSec group authentication off of an AD domain controller.
Recently I have been having some issues with some of the client machines, and I can't for the life of me figure out what the issue is. Some machines will not respond to pings, and I cannot remotely access the machines (using Dameware Remote Control) while they are connected to the VPN. Other client machines work fine. In fact there have been a couple instances where I have two machines in a remote office, using the same internet connection, both connected to the VPN, where I can ping and remotely manage one machine, but not the other. If RDP is enabled, I can sometimes get into those problem machines via RDP. But this is crippling our ability to remotely support many of our VPN users, and I just don't know what to look for.
I have tried disabling Windows firewall completely, and that does not seem to work at all. The only other thing I can think of is I recently upgraded our McAfee software. But it does not prevent us from getting connected to or pinging any of the systems on our physical network, nor to half of our VPN users. Most of our clients are running Windows 7, or Vista, and using the client version 5.0.07.0290, or 5.0.05.0290. Most of the clients using 5.0.07.0290 are using the 64-bit version.
I need to create a network bubble..means..Let say I have 4 machines having IP address 10.1.1.1,10.1.1.2, 10.1.1.3 and 10.1.1.4 (these are not actual IP's, using them just for explaining). These machines are connected to public network. At a given point in time, I need to isolate these machines from the public network in a way where - All these 4 machines can talk to each other using the assigned IP's. - These 4 machines cannot talk to any other nodes in the public network. no other machines outside these 4, will be able to ping these machines.

I am having a very strange issue with connecting new machines to reach the internet.We have a ASA 5505 which the previous tech configured the DHCP pool to 192.168.1.60 - 192.168.1.110
We ended up reaching our limit which I changed it to: 192.168.1.60 - 192.168.187
Then next day when I arrived to work, our DC was hung from windows updates. Once we got everything back up, every computer currently on the network can reach the internet/VPN tunnels etc. So (continuing with my day) I created a new server in a VM (Hyper-V)I can ping everything internally (even the router) 192.168.1.1, but I cannot resolve DNS. I have configured a static IP, tried Dynamic IP.I have looked for any ACL indicating to block outside the range of the old DHCP pool but no luck.On my local maching I can ping the DNS addresses, but just not on the new server.

Running Windows XP Im a bit Dizzy as i can't seem to workout what's going wrong or what im doing wrong lol!!!8 Pc's on the network, all can view files etc.apart from one Pc Lets just call this "Bob1"It keeps asking for user name and password, now there's no user name or password on the giving pc, file and sharing is open and all the right ports giving. what i can't understand is that the reaming 7 pc's on the network has the same setup and files permissions, on the same subnet and can ping each other to my knowledge.So just to prove myself wrong i made a password for the pc that was asking for one on the network and this still did not work.so to cut the story short 7 pc's can search each other fine but on "Bob1" keeping asking for user name and password.

View 3 Replies View RelatedOn my home network, I have several shares on my PC. But I dont seem to be able to even view the shares from other machines. If I put the IP address into an explorer window (\192.168.0.4) on another machine I get the message: "\192.168.0.4 is not accessible. You may not have permission to use this network resouces. contact your network administrator etc etc". So I cannot even bring up a directory list. There are no problems for me connecting to network shares on other machines from this machine that is refusing connections. That has all happened since I reinstalled windows. I reformatted the system partition and since then I cannot get the shares working again (they used to work fine). The shares are in a data partition that was not reformatted. This is really winding me up, as there never used to be a problem, and I cant think of anything else to look into, short of delving into the registry, and I wouldnt know where to look.
View 3 Replies View RelatedOne of our servers has lost the ability to access WAN side computers. For example, it can't ping google.com. It can, however, interact with LAN computers. One thing of note -- it is set up with a static IP and one-to-one NAT on the firewall (sonicwall)When we disable the one-to-one nat on the firewall the server is able to ping out. We do need to keep the one-to-one nat up though -- as it provides access to the site the server hosts

View 2 Replies View RelatedI have 3 machines running windows XP, they all belong to my company's domain. These machines have to leave our office but still have to be able to connect to each other and share a few folders on each. I used to do this all the time. I would make sure to turn on the "Server" service, set the windows firewall to allow File and Printer sharing, set the File and Printer sharing setting in the Local Area Connection properties, and set the proper sharing/security of the specific folder. Then as long as each machine used a specific local logon name that was the same on each machine, they would all connect to the shares and work perfectly.However now, I seem to not be able to get any of this to work on machines that have service pack 3. Is there something in sp3 that breaks this?Isn't there a way to still share files on these sp3 machines even though I'm not on the domain? (without changing the domain membership)

View 6 Replies View RelatedI'm having problems in a mixed XP Pro (SP3)/Win 7 Pro (64 bit) network getting the XP machines to access data on the Win7 box. The XP machines are connected wirelessly to a D-Link DSL-2640R router modem and the Win7 machine is connected via an Ethernet cable.
Internet access from all machines works perfectly.The two XP machines can see each other either via mapped drives or My Network Places and can access files.The Win7 PC can access data on both the 2 XP machines.All machines are part of the same Workgroup and the network is set up as 'Office' on the Win7 machine.The XP machines can see the Workgroup, including the Win7 machine after I changed the network type from Home to Office, but can not access the data on it.I assume this is a permissions problem on the Win7 machine. I've made the root directory of the HD in the Win7 machine shareable as \Hppro3125hd via Advanced Sharing/Properties and in the Advanced Sharing tab I have set the permissions for Everyone to Full Control.
There is only one user (Garry) explicitly set up on the Win7 machine. I've tried connecting to the Win7HD via a mapped drive on each of the XP machines by logging on as a different user i.e. matching the user name from the Win7 machine but still no joy.Is there an easy to follow step-by-step guide to lead me through the necessary steps to allow the XP machines to access data on the Win7 box?

Once again the sun sinks into its nightly reprieve; for the third time since I first set out on this mission. Before me, only the piercing glows of monitors that sting my eyes. Yet, I cannot look away. The clacking of keys, once triumphant battle drums of purpose, has grown sharp. They pierce my ears and my mind. It would be madness to continue. My body is weak. My resolve is waning. My sanity ...... tenuous. But if seeing this through means madness.....bring on the madness.
I'm trying to find a way to network my desktop (wired) and my laptop (wifi) so that I can swap files between the two easily. I've mostly been attempting this through Windows Homegroup, although I've also downloaded and installed TeamViewer. The thing is, the two just will not connect. After much poking around I found the specific symptom to be that wired connections and wireless connections refuse to speak. My laptop sees my roomie's laptop easily enough, though. And if I hardline my laptop to the router suddenly their best friends! - joining each others' Homegroup, swapping files, trading recipes!
Points of interest: I've noticed that, while both are enabled, only IPv4 connectivity indicates internet access; IPv6 says No Internet Access. Pings from one machine to the other result in "Request timed out" or "Destination Host Unreachable." I've disabled firewalls - Windows and the one on the router. Disabled and then uninstalled anti-virus. I've updated the router firmware and net adapter drivers I tried restoring router to factory settings, in case I changed something I shouldn't have along the way. I've alternated static and dynamic ip addresses - no difference there. I've just spotted a couple of errors in the Event Viewer that look like they could be leads;(!)ErrorDhcp-Client The IP address lease 192.168.2.2 for the Network Card with network address 0x6CF049E337F0 has been denied by the DHCP server 192.168.2.1 (The DHCP Server sent a DHCPNACK message).
