We have three 2003 domain controllers. One of them had some issues and while it was unavailable the other two reported the following:
This computer was not able to set up a secure session with a domain controller in domain xyz due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems.
Some users reported problems with applications etc (anything that used AD). Were these errors meaning that the two remaining DCs were unable to function and thus the users were having trouble, or were they merely saying they tried to speak to the 1st DC and couldnt, but everything was OK after that (in which case the users having trouble were only the ones using DC1 at the time) ? In other words, did the other two DCs take over and carry on or was AD unavailable entirely?
