But most people don't have this problem...

Are you sure that the service is actually running?

You do know that the clients need the Services file entry too?

Do those machines happen to be running Win2K SP3? It messed up remote
services and got fixed by SP 4.

Are you sure that someone has not firewalled port 3050 on the server or the
affected clients? For example, has someone installed an update for Norton
Security; or reinstalled it?
