Over the last couple of days, set up a new Dell Poweredge 1900 for a client running SBS 2003 Premium R2 (2 NIC config). Although not our main line of business, we do 5-6 SBS installations a year and have never had any major issues.
However, on this install none of the clients will connect to the SBS server. Whether we use //servername/ConnectComputer or Right-click on MyComputer and attempt to add to domain, it fails, the latter with "The network path was not found".
Other salient points:-
Client PCs are happily using the SBS server as a proxy and can access the Internet fine
Attempts to browse the server, either by FQDN or IP address, fail - again with path not found.
Pings on the server name AND IP address work fine
Client PCs are getting their IP address from SBS server DHCP
Re-ran CEICW, but made no difference
ISA 2004 SP3 installed
Many threads that we have seen over the last 24 hours mention DNS as a likely cause, but (a) we have only got DNS as SBS self-configured itself and (b) The fact that \\IP Address fails almost feels like a firewall issue ???
As always, any help or guidance appreciated
