Hi There,

My SBS 2003 Server, all of a sudden has stopped accepting anything.

When i double click on network drives it says that it cant find the server (From a client PC)

I cant ping the server from any other pc
I cant go to the web address of the server.
Exchange wont connect to the server.

On the server itself, everything appears to be going fine, I can access OWA locally on the server, and can access and ping other computers and devices on the network.

No idea what has happened to it...

Would anyone know how to fix this? :)

Perhaps some changes in the IP configuration on the ethernet adapter you are not aware? Or the Firewall rules were modified to block everything? Any third party software installed lately?

When you try to access the server from a client, does it work if you use the IP address instead of the server name (that would indicate a DNS issue)?

The first question: has anything changed recently?
Second question: have you looked in the event logs?

Try adding the registry key as described in

and restart the server

Obviously you should check the event logs first to see if this really is the cause of the problems. :-)

Had a very similar situation awhile back and it turned out to be a port issue.

What had happened was the DNS Server service had started before the ipsec service had and assigned itself the port that ipsec needed.

Quick fix was to stop the DNS server service and then start the ipsec service, then restart the DNS Server service.

The long term fix is to exclude the port for ipsec from the range DNS can use (I can't remember the port numbers but there is a MS KB article for it)
