Works fine on my SFV/100 .. There's no need for a special application
"tweak" (I assume the two computers are connected on the LAN side...)

Can you ping from one host to another? Are they all DHCP or static IP.
Have you tried using the search/find computer to locate the other
computers on the LAN? NetBIOS doesn't like it when IP addresses changes,
and using Search (W2K, WXP) or Find (W9x, NT) will clean up the local
name database does usually get your network browsing working again.

Hope that helps ...
