I am receiving the following errors on a laptop that I have recently added to our domain. The laptop is located at another location away from the server and connected by a wireless link. It is located on a different subnet other computers, laptops and PC's have not had this issue. I have checked DNS on the server and it lists the laptop I am having the issue with. Also on the laptop the DNS server comes up with the correct IP for the SBS server. The system just hangs for several minutes when logging in and then can't access the SBS resources once it does. The laptop was working fine on Friday prior to being shutdown for the weekend.
The errors in the event viewer are as follows:
Windows cannot determine the user or computer name. (an internal error has occured) group policy processing aborted.
The security system could not establish a secured connection with the server DNS. No authentication protocol was available.
The security system detected an attempted downgrade attach for server. The failure code from authentication protocol Kerberos was "there are currently no logon servers available to service the logon request)
From what I have been able to find this could be a DNS issue I suspect but I am not sure on how to correct it. If any of you suggest a DNS issue please be specific on what I might need to correct it.
We can use VNC from the other location np to access the laptop by name, that is something I thought might be useful as well as that would tell me that the DNS has to be working I would think? Also I have upgraded the network card drivers and tried both a wireless and wired connection.
Thanks in advance for your assistance.
