all of a sudden the network shares are not showing up on the client computers. They are trying to access the shares on the server through their usual mapped connections.
I did look at the server and the server service was off. I turned that back on. On the server I notice that when I go to browse the network under Entire Network > Microsoft Windows Network I get the error "Unable to browse the network The network is not present or started.
I should note also that the internet went down recently and there is a sonicwall on the network that was rebooted.
Another thing I should note is that there are two servers on this network and I notice in the log files there is an error that says "Multiple domain controllers running Windows Server 2003 for Small Business Server have been detected in your domain. To prevent this computer from shutting down in the future, you must remove all but one of these from the domain."
This may be another issue completely, but there are two SBS 2003 servers on this network.
