account lock out problem

[Sameh Ahmed]

Hello there
we have an account lock out policy in our domain, sometimes users are locked
and auditing shows that they have failed authentication from a client that
happens to be a domain controller and has no softwares configured to
authenticates on behalf of users whatsoever.
this really confuses me and causes many problems as this happens
continuously even when I unlock the user it locks in a few minutes.
any ideas?
Regards
Sameh

If you have not read
http://www.microsoft.com/technet/tr...ndowsserver2003/maintain/operate/BPACTLCK.asp
do so and see if it can help. Another possibility would be a troyan or virus
trying to break in to your account on server. Check your server.
