I am having very weird issues accessing some of the computers in our workgroup. Some of the computers can’t see other computers in the workgroup. The strange part is that they can ping by IP and by Name. Using run \\ComputerName wont find them but run \\ComputerIP will work fine.
The computers that can’t be reached don’t have any problem from there end and can be reached by most of the other computers.
We recently “upgraded” the DNS/DHCP/WINS server from Linux to Windows server2003.
