>>Any ideas on where to look for culprit (or a scapegoat, never mind)? The next thing I have to tried is to move everything to the new machine and use that one as a server, though it's the solution I don't particularly like - it's the boss's machine, and bosses are probably not the right people to sit at the server. It worked fine, though.

If any NT box is available, Workstation or Server, make -THAT_ the Browse Master for the network.

Thanks, that's probably the layout. Will try first thing on Monday.
