There are two domains in my network that just disapered. After putting these domains in Computer Browser, I could see the domains, but when I enter in the domain it is not possible to find any machine. I ran a Resource Kit application called "DomainMonitor". In these two domain the message was "could not find any PDC". What are the troubleshoots that I can make solve this problem? Thanks in advance.

How many domains are in your network? Do you have trust relationships between the domains? Are you sure that these domains are on a subnet that you can reach through some sort of gateway? Are there other domains on your network that you CAN see?More info please. . .

I would check my WINS database and see if the computers are listed in WINS. If they are not listed then you can add a static entry for each computer. Also, I would make sure that the computers have the proper IP configured for the Primary WINS server.

Sounds like you have a very large and pretty complex WAN. Are the connections to the two domains you can't see slower than the other 8? It really sounds like one of two things - name resolution problem or slow connection such that browsing is just too slow to create a browse list. Can you ping the hosts in the other domains by name? If you can't ping, then it's clearly a name resolution problem first. Look at your DNS or WINS server(s) in these domains, where they are and whether they are configured properly to resolve names beyond the gateway, and whether your local clients and WINS/DNS servers are properly configured to forward requests to the other domains' servers. If you can ping by name, it's probably just a slow connection problem. See if you can map a drive to a shared resource in the other domain(s) and access it that way. Sometimes if you have a slow connection this is the only way to get to a resource quickly because browsing is just too slow. Hope this helps!
