No connection to Server

I'm having problems with one of our DC's (We have two) - it has no
connectivity. I'm unable to ping it by name or IP and unable to ping any
names or IPs from it and suspect it's a DNS issue. I've been through the
event logs and seen a 4319 NetBT error and 5781 NetLogon errors which I've
read related to Servers with 2 Nics - the Server does have 2 Nics but one of
those is disabled.

Below is the NetDiag Output, I have rebooted the server, checked DNS is
running and checked for W2K3Server1 entries in DNS - can anyone advise on
next steps?

No it isn't DNS.
If it was DNS you would still be able to ping by IP#.

Possible causes may include:
1. Bad cable
2. Bad Switch port
3. Bad Nic
4. Mis-configured TCP/IP settings
5. Corrupted Nic Driver
6. Corrupted TCP/IP Stack

There is a name for this that I use....it's called a mess. You *really*
need to reconsider whatever it is that makes you think you have to configure
the nic this way. The nic is identified by the Primary IP#. This number
will be the first one applied to the Nic and it is the one you see when you
go into the *normal* TCP/IP setting without going to the Advanced button.
The Default Gateway must be the same subnet as this Primary IP#.

This might be the root of your problem,...and it might not,...but it
certainly would be an aggravation to the problem. There is rarely a
justifyable reason for a NIC to have more than one IP#,...particularly when
the IP#s aren't even in the same subnet. There is almost always a better
and more cleaner way to handle it that involves having only one IP# on the
Nic.
