I've set win98 computers up on our LAN (win NT 4.) w/no problem. Now we got
an XP & it appears to be part of the "workgroup" rather than part of the
"network." That is, when I go to another computer on the network & look at
Network Neighborhood, he doesn't show up. He's one level below in
"workgroup."

He can see server, can get on internet & email, but we can't use our
messenging system ...

What did I do wrong & how can I correct this?

TIA,
Sherry
