I get the same sort of problem too. If I try to click on NetworkPlace -> SharedDocs for the same machine, the window hangs, then goes into "not responding" then If i close the window, explorer.exe crashes and I have to restart it using task manager

Actually happens with all shared folders on same machine. Also, I have another XP machine on network, I have shared a couple of DIRs, when I try to access them from another computer, I get a prompt box asking for password/username for $IPC share ??

Does anyone know of these things? thx
