can’t see SBS 2003 in network neighborhood

[DougP]

Our main Windows 2003 SBS server can’t be seen in network neighborhood.
If I Ping its name it \\servero2 I get this response
Ping request could not find host \\servero2. Please check the name and try again

If I ping one of its IP’s, it comes back OK

To map a drive or connect to a shared printer I have to go to Start, Run and type in \\Servero2 , hit enter, then choose items from the folder that opens. Right click to connect to a printer or right click to map a drive. Its this way for all computers in the network. We can see each others computers and an old 2000 Server which is now just a machine to remote into. But not the main server.
Is this a security thing?

Any ideas?

Are all your workstations in the same subnet mask and uses the same DNS as your main Windows 2003 SBS server?

the server has DHCP running, I just noticed in this dump it says Netbios over TCPIP is disabled(at the bottom)? is that why?

Also What is this DNS IP? > 198.31.248.3
I googled it, looks suspicious

Have you tried the following?

ping 192.168.1.3

Or:

ping OHCNET.LOCAL

So I assumed you don't use a login script to map network drives, correct? You may want to check if the ICMP port block or not.

 

[DougP]

Yes my original post
here is my conclusion:
Any IP's come back fine, any words don't come back. is that netBIOS?

Pinging ohcnet.local results in:
Ping request could not find host ohcnet.local. Please check the name and try again.

Okay, you may want to try configure or take a look at your DNS Reverse Lookup Zone.

...Also your DNS forward lookup. Your Computers should always have DNS be set to the SBS server ONLY. The SBS server should provide DNS lookups for local and remote (Public Internet) zones by default.
