Server not in Network N’hood

I’ve a problem with a windows 2000 server connecting to an NT 4 domain. From the NT 4 server, i can run the C$ of the 2k server etc. but cannot browse through Network Neighborhood. Even from the Windows 2000 machine, My Network Places does not include the 2000 server but does include the NT server! I know this is some registry entry issue and is probably caused by the system policy somehow but i can’t find a fix.

any help is much appreciated.

thanks in advance, gary
