Ok this little puzzler has stumped 3 techs.
It goes like this ... we have 2 comps run on a 98SE network using 3com 100\tx cards. The network has always worked untill just recent.
Main computer has net connection
sub (other) computer is direct connected to main comp
Problem:
The sub comp can access the main comp without any problems at all. It can write to the hard disks, it can read from the hard disks, it can transfer files and the like.

The main comp sees the the sub comp and sends info during games, altho laggy. However when the main comp tries to access the sub comp's hard drives, which are shared, it freezes the main comp.

The machines have different IP addresses on the network. have different names and the same group name ... on the outside everything looks fine ... but it kills the main comp every single time it tries to access the sub comp .... help would be greatly appreciated ... thanks much all you gurus out there.
