My current company domain consist of multiple locations. Each location has a different subnet mas and are connect to each other through a vpn router. So for example: Location A would be 192.168.10.x, Location B would be 192.168.20.x, Location C would be 192.168.30.x, etc....
the majority of our user workstations run windows xp SP1 through Windows XP SP2 with the lastest updates. For those pc who have SP2, I have enable file and print sharing as well as remote desktop in the windows firewall.
Now, here is my problem. If I try to connect from one pc to another pc on the SAME subnet mas VIA windows explorer using this command: \\computername\C$\
I can connect to the users C drive and view all their problems. If I try and do the same thing to another pc in a different location (which uses a different subnet mas), I am unable to attach to their C drive nor to their pc VIA windows explorer. Now, what does work is I can remote desktop as we as pc anywhere to different location pc with no problems. If I pcanywhere or remote desktop to another location, then try the same pc that gave me the problem the first time, it works fine for file and print sharing.
So basically what I am asking, what would cause each location not to connect to another VIA "\\" and how can I resolve this issue. I should add, that we do have windows 2003 servers in which any pc reguard of location can do a "\\server" command and view shared files with no problems.
It just seems to be an XP problem that I am struggling with.
