I've been fighting with this thing all day and parts of last week. I just don't know what to do. It's a Windows Server 2003 R2 SP2 box. It's fully updated and has been working fine for a long long long time. The only issue I know with it is a failed hard drive in one of the bays. Its replacement should be here by the end of the week but I don't see how that could cause network issues. That issues aside, here is what happens... I can ping the server from any machine on the domain. I can remote desktop to the server but I can't browse it's drives (in other words I can't browse via \\servername\share) and I'm a domain administrator so it shouldn't be a permission thing. If I'm remoted into the server, I can browse out to any other path on the domain and I can ping all other machines. All of the machines have the firewall disabled as well. The errors in the event log are no help. I get DCOM errors (dcom 10006 the rpc server is unavailable) and normally DCOM or RPC errors only want to be fixed via reformats but I can't do that. I'm just lost here.
