By looking at the logon failure audit event logged at the same time as the SPNEGO event, more information about the logon failure can be obtained. Windows XP performs a reverse lookup on the DNS Server it is configured for as part of its own blackhole router detection. In the case where the DNS Server used does not have the Reverse Lookup Zone and/or no PTR Record for their DNS Server, the request gets forwarded out to the Internet.
The response comes back with one of the following server names:
prisoner.iana.org
blackhole-1.iana.org
blackhole-2.iana.org
These servers own the public PTR records for the 192.168.x.x zones. Since they have no record of your DNS Server, they reply with a "Server does not exist" reply, which causes LSASRV to log the error.
Solution: On the local DNS Server, create a Reverse Lookup Zone, and enter a record for your DNS Server.
Anothe case: The client was pointed to the ISP's DNS servers which contained a zone for the customer's domain. We removed the External DNS server addresses and ensured that DHCP was only assigning the Internal DNS server address. For testing we manually configured the DNS server address on a workstation which overrides the DHCP values. We can reference the following Knowledge Base Articles - Q291382 Frequently Asked Questions About Windows 2000 DNS.
Another case: Check the time on the workstation. Ensure that the day, time, time zone, AM/PM, year are correct. In my case the year was incorrect everything else was correct.
Last case: In this situation they actually were not authenticating to the DC. They were being logged in with cached credentials.
Had this on a WinXP workstation which could no longer access domain resources. The fix was changing the DNS settings to point to a Win2k DNS which was tied into Active Directory. Apparently the workstation could no longer locate SVR records for the kerberos authentication server. These records were not in our UNIX DNS but were in the Win2k DNS.
