If you have a lot of servers to go through, using the "qwinsta
/server:server" and "reset winsta session /server:server" commands MS
inherited from Citrix might also be useful.

I also recall an issue some years back with sound drivers locking out
accounts. I don't think this is still the case in this day and age, but if
you have an old Compaq PC on the network it might still play a role:

There are also a number of issues in a distributed environment that can
cause lockouts, or apparent lockouts. These almost always involve password
changes in my experience (and apparently in quite a few other people's
opinion.) I'd scour the event logs on the PDC emulator for the last
password change for the affected user and work my way from there. As some
other people have suggested, LogParser
(http://www.microsoft.com/windows2000/downloads/tools/logparser/default.
asp)
can be really useful for automating that task. You can then use the MS KB
articles to help you on your way - they're sometimes a bit cryptic, but
there is a lot of information available in them.

Wrt determining if a domain user is logged on INTERACTIVELY onto two
stations at the same time, the only sure way would be to query each
workstation directly. I'm sure there are various tools available for this;
one of them is psloggedon by SysInternals
http://www.sysinternals.com/ntw2k/freeware/pstools.shtml. (This tool might
also be useful in a TS environment.)

Hope that's useful to someone.
