Windows 7 machine invisible to network despite firewall off/wide open shares
Posted on 2011-04-26
I recently installed a Windows 7 Professional computer to a small office (two other computers) configured in a workgroup. I have two shares off this 7 machine. One is a folder of files and the other is an Act! 2011 database. For the first day or two things worked fine in terms of shares. Then suddenly the other two machines can no longer connect. I went onsite today to troubleshoot and found the following.
- The Windows 7 machine is functioning normally. It has full Internet access and can see other machines.
- The other two machines (XP) can no longer see the 7 machine. Any attempts to access previously used shares result in a "Can not be found" error.
- Rules from the firewall (Remote Access) can no longer access the Win7 machine.
- The Win7 machine no longer responds to pings to the IP and can not be found by IP.
The Win 7 machine is on a WPA-PSK wireless network. As I stated before, it still has Internet access even though it no longer appears to be live on the network. I have disabled the firewall and it had no affect.Computers on the same network can not communicate with it at all. There are no third party firewalls on the machine.
There is one error in the system log aside from a NetBIOS error regarding applying the Workgroup name to the "IP address" because another computer on the network "IP address" refused the name, but I'm not sure how that would affect my ability to ping by IP.
So far my guess is that this is some sort of bug related to Win7 and the WPA-PSK wireless network. My next course of action is going to be to run a cable, but I figured I'd check here first in case anyone has seen this or has other ideas to check out.
