We implemented a new Small Business Server 2003 on a 15 workstation network. Everything was working fine for about two weeks, when all of the sudden the NetBios name of the server stopped showing up in the directory. I.e. when you go to My Network Places (from the workstation or the server itself) and look at the domain, all workstations show up, but the server does not. The server was showing up for those two weeks.
The server can be accessed normally in all aspects. What I mean is, if I go to a client and type \\servername, etc, then I can access all resources.
Also, we cannot pinpoint any changes that were made to the server that could have killed this.
Other possibly pertinent information...
The server runs RAS.
On ipconfig /all, the node type is unknown.
In the registry, the EnableProxy value is 2.
An article on Msft's KB stated to go to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netbt\Parameters\
I set the EnableProxy value to either 0 or 1, but whenever I reboot the server to make this fix, it automatically defaults back to 2.
Normally, I would probably just live with this problem and go on, but the client would like to be able to see the NetBios name.
I'm at a loss here. I appreciate any help that anybody could give me. Please let me know if you need more information.
