I am having an issue trying to access my Active Directory on my Server 2008.  If i log off i get an error that i cant find a user account to login to the server. If i restart the server it works fine. This just started happening out of the blue.  

I am also getting an error message  see attachment.

Start the TCP/IP NetBios Helper Service, This should fix your issue, I had this issue once. I cannot remember why it was this service. I think it needs it for replication although it doesn't really use it.

Some reasons why it may need this:

1) Legacy clients such as Win9x & WinNT require NetBIOS resolution to find
resources in a Microsoft Windows network
2) Legacy applications requiring NetBIOS resolution
3) 'My Network Places' browsing (formerly known as 'Network Neighborhood')
4) External trusts with NT domains
5) Cluster service issues
6) Exchange server issues sometimes
7) NetBIOS is required to restrict a user to using a specific "computer" or
"set of computers."

Is the time on the machine and the domain machines properly syncronized? RPC service running?

The "RPC server unavailable" error can occur for the following reasons:

DNS problems

Time synchronization problem

RPC service is not running

Network connectivity problem

Procedures for Troubleshooting RPC Server Problems
See "Troubleshooting Active Directory-Related DNS Problems to identify and resolve DNS issues."

See "Troubleshooting Windows Time Service Problems" to identify and resolve time synchronization issues.

If the RPC service is not running, start the RPC service. If the RPC service is running, stop and start the RPC service.

Verify network connectivity and resolve any issues.

Log Name:      DNS Server

Task Category: None
Level:         Warning
Keywords:      Classic

Description:
The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.
