Server Name Changed after update

Question

I'm new to SBS 2011 so I don't know much about it yet.  I updated a server for a client and when the server retarted the name for the server that showed up in the Network had changed.  It's now showing up as WIN-P0NIHSQCMU2.  I tried restarting
from the last know good configuration and that didn't work.  The biggest problem is because the name has changed no one can gain access to the server over the network.   Any help or advice would be much appreciated.

Hi:
First, it might help the community to know what updates were applied and you see any errors in the logs that might be helpful.  I would create an image of the system as it is now for possible future troubleshooting onto fresh media using such as acronis
or preferably shadow protect, both offering free trials of their product.  Note that you want to do this from a bootable CD of their product created from their ISO. 
Then, depending on what errors I see I would restore the entire system from backup or alternatively try just restoring a system state backup less than 60 days old, preferably either that existed just before the updates were applied.
Since we don't know what happened, I suggest to everyone on this forum that systems, particularly servers, be rebooted and the event logs examined before applying updates to check for errors that have already crept into the system.
