XP Hangs when logging in when connecting to 2011 SBS
Hello,
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.

Yes the right DNS server is there, it is configured through DHCP and I verified its the SBS and it is. I can ping the server for sure as well from that laptop. the laptop did connect fine last week, it seemed like after it was rebooted is when the problem occured.
can you try to rejoin the domain?
ASKER
Just had another computer now show up with the same problem. These are the last two that were added, not sure if I should start a new question. Do you recommend readding both of them?
no i wouldn't
and you are 1000% sure dns is working fine?
if you ping servername, it gives replies?
and if you ping servername.domain.suffix ?

I can ping servername.domain.local yes. Do you recommend anything else I can check to ensure DNS is working?
one other question, where is the dc pointing for his dns?
it must be pointing to itself (127.0.0.1)
it must be pointing to itself (127.0.0.1)

The server name has an address that is used on our local network. For example our server is called dfps01 and has a host entry in the DNS of 192.168.5.25 which is the server's IP address on our local network. dfps01 is the SBS server IP address. We have had this installed since Feb. this way and these two workstations are the first issues we have come across, is that the information you were requesting? From what your saying this entry should be 127.0.0.1 on the server itself? Should that have caused other issues before though?
check the network interfcae properties on the dc, and check wether it is pointing to itself in the dns section of the properties (127.0.0.1)
ASKER
It is pointing to 192.168.5.25 the IP of the server. This should be 127.0.0.1 your saying correct?

Figured it out myself which is why the solution is from me.
The xp client, does he have the right dns server configured? that is the dc?
and if so, can you once logged on, ping to the fqdn of the sbs?
