Hello,

One of our servers is not seen in the network. The server works fine, you can access the shares and we have a database in it that works properly. The problem is that we cant connect to the SQL from Microsoft Excel how we used to. Since this stopped working, you can no longer see the computer on the network like you used to. All of the other computers and servers are listed under 'Network'. This one used to be, but isn't anymore. How can we resolve this important issue?

How can you verify that the server is on the same domain?
Verify that File and Printer Sharing is ON?

This sounds like a problem with the browser service.  If you have more than 1 machine that thinks is is the "master browser" then machines can get "lost".

You need to determine which machine(s) are running as master browsers.  The technique for doing this is different between a domain network and a workgroup network.

Yes, file and print sharing is enabled, the server is part of the domain and I cross checked the NIC  advanced settings.  This has worked for years and suddenly disappeared a few weeks back.

Jestertoo, how do I check the master browser status?

Also, if it makes a difference, the server can not even see itself on network (yet sees all the others on the network).

Try this in a command window.  It works in my workgroup (don't have a domain configured at the moment).

for /f "delims=\= " %C in ('net view ^| find "\\"') do @echo -Checking %C && @nbtstat -a %C | find "MSBROWSE"

When I did that (from the server), it came up with about a quarter of the computers on the network and had '-Checking' in front of them.

Were none of them followed by the message "..--MSBROWSE--..<01>   GROUP     Registered" or something similar?

Were these machines the only ones actually powered on and connected to the network?

If not, then it sounds to me like it is definitely an issue with the browser service.

Is your network a domain or is it one large workgroup?  I believe the command I cited would work on either, but I will try to confirm that.

Yes, this is a domain...

I did see "..--MSBROWSE--..<01>   GROUP     Registered". It had its own line, some of the pc's were above and some below it..

OK, that pc is running as the master browser.  Hopefully, it is the PDC in your domain.  Do you have any subnets in your network?

On the server see if the "Function Discovery Resource Publication" service is running.  If not, at least as a test set to automatic and start the service.
