My w2k PDC is not showing up in Network

I’ve w2k PDC server with DNS & WINS. This is the only domain controller. I’ve w2k, NT, 98 clients.

The problem is that my W2k PDC is not showing up in Network Neighbourhood on any PC. Logon authentications are being made successfully. Even sites hosted on this w2k PDC is running. we can access this pc by typing \\pcname in network neighbourhood (NN).

Its just not showing up in NN, but anything else is fine including DNS, wins,. …etc

I’ve also reinstalled DNS & wins. but the problem is still there.

So any one of u have a solution to this problem?
