I have an weird problem happening on my domain LAN. I have 2 offices that are connected through a WLAN. I use VNC to connect to the satellite office over the WLAN. However, I cannot use VNC to connect to any computer in my local office over LAN. To investigate, I've tried to go into the command prompt and ping the IP addresses of the computers, however I am failing the pings. The computers I am trying to ping to are on the network, registered with DNS, can connect to internet and network drives/programs with no problems.
Windows Firewall is off. Offices run on Windows XP SP3 environment. I do not know of any GPO that can set the ping to give failed response. VNC works fine connecting into the satellite office. The ping problem spans both offices. When pinging a computer name it will also resolve into the correct IP, so it is hitting DNS with no problems.
HERE IS THE INTERESTING PART OF THE PROBLEM. I can ping all connected SERVERS on my network. Just not the workstations themselves.
Can anyone tell me a good way to investigate why without disrupting the system as it stands?
