Event ID:5719-Netlogon on Windows Server 2003

I am getting a error while trying to access a member on my server. I am using a Windows 2003 Server using Terminal Services. I am not able to find out any solution for this. The error is related RPC server not available, no netlogon server and invalid network address. While the DC is working quiet fine and there is no problem with the login.

In order to gain access to the terminal server the user must have account or should be the member of group who is allowed to manage remote desktop. You can find the group RemoteDesktopUser in AD. I think after fixing that the problem would be resolved. The next thing you have to do is to check out the dns settings.
