I have a similar problem to Random.
I am linking (peer to peer) some W98 machines and an XP machine. The W98 machines communicate to each other well, but the XP machine only communicates sometimes.The XP machine seems to lack netBUEI protocol, and microsoft family logon, even after installing all the networking tools off the XP Home CD.
If anyone can tell me how to find and install netBUEI and microsoft family logon, in XP, it would be appreciated.
