From: Drew Boillot on 18 Feb 2005 10:00 Hello, I have a few PCs that are in use after hours that they seem to just, lock up at 5:45 like clock work. On all 3 of the PCs, i get errors like the following, -----Start Error(s) The Security System detected an attempted downgrade attack for server cifs/ntserver. The failure code from authentication protocol Kerberos was "There are currently no logon servers available to service the logon request. (0xc000005e)". ------------------------------------- The Security System could not establish a secured connection with the server cifs/ntserver. No authentication protocol was available.

I'm not sure what is going on, but i see these errors at the time the PCs get sluggish then locks up. can anyone tell me what to do.. or at least where to start looking?
From: Raoul on 18 Feb 2005 10:39 If they consistantly lock up at the same time, the first thing I would look at is the task scheduler to see if anything is scheduled to run at that time of day.

From: Drew Boillot on 18 Feb 2005 18:03 This is the first thing I tried. I even changed the antivirus scan times. I will try the things suggested in the next post Monday.
