Host hang

Still having trouble with my host pc hanging when files
are accessed or sometimes when saved. I'm using a wired
ethernet system to get two pc's together. They can both
see each other on network and can access each others
shared files. But the host will often just hang when the
client accesses a file.
Things I've checked and done are, removed and reinstalled
card drivers, checked psu, cleaned fan, added extra 128
ram even reformated the host pc (graet fun!), removed the
firewall and anti V. Still the same problem. I'm using win
98se by the way. Really strange because everything seems
to be configured ok just this hanging problem. Has anyone
got any ideas?
