We havea corporate domain, and are experiencing an issue with one of the
administrator accounts.  It constantly locks/disables itself, and it takes
less than 10-20 seconds from the time I go in (another admin) and unlock it.

At first we thought it was a problem with his phone synching with Exchange,
but we have eliminated that variable and it still occurs.  Furthermore, when
checking the security section of the event viewer on the domain controller,
there4 are no associated login failures which would cause an account to be
locked out.  I have enabled the account, refreshed the event viewer, ... no
failed attempts, then looked at the account again and it is locked out.  All
of this happens in 10 seconds or so.  I am not sure what else I can check as
the only policy we have in place to disable an account takes place when there
are 3 failed logins.

Any other suggestions I can look at or investigate?  The DC is Server 2003
and the system the other admin uses is an XP machine (but I do not beleive
that is relevant).

I would love to hear from any of you, thanks in advance.
