Event ID: 5781
Source NETLOGON
Type Warning
Description Dynamic registration or deregistration of one or more DNS records failed because no DNS servers are available.
Comments This error may occur in several circumstances. See Q259277 for a general approach on troubleshooting this error message.
The event can also be caused by start of NETLOGON service before DNS if hosted on same Domain Controller - see Q193888 - adding DNS as a dependency for Netlogon service - (link below)
One particular condition is when a DNS server running BIND is used a forwarder in a Windows 2000-based DNS. Due to its behavior on caching DNS records, a response to a DNS query made by a Windows 2000 server to dynamically register a client computer name may appear as not being authoritative (even if it is). In this case the Windows 2000 server informs the client that the request failed. As per Microsoft, this problem was fixed with SP1.

Went through all of it allready , nothing worked.

Is your DNS server using itself as it's primary DNS server?

Yes it is.

Did you enable fowarding? This is always a good idea :)
