When this appears, no one log on to the server. This problem happens a few times in one week. We have the problem on all our 4 Terminal Servers. Microsoft has at this momment no solution for this problem. Thuis is a big problem in our organisation. I hope that one of the memmbers can help us.
Is this to say that you have opened a support case with Microsoft?
What software is installed?
Do you have any other similar machines? (preferably matching in OS/Edition/Bitness as well as hardware)
