I have a DC with Win2K. It has DNS and WINS configured. The clients are win 9x distributed over various workgroups. Everything was working fine. Suddenly, from one of the workgroups (say X), the clients are not able to browse the network neighbourhood. I tried to change the workgroup to Y. It worked. But from this particular workgroup, it is not working. I also tried to put some other PC to workgroup X. But even then, the network neighbourhood does not work. Any suggestions....???
