Vista - vista password change account lockout

Interesting problem here:

I've had Vista on my machine for a while now (I'm the departmental
guinea pig). I changed my password as requested by policy yesterday.

As of today my account is locked out. I requested MIS reset the
password, they did. As soon as I restarted the machine, that was
locked out too.

I checked the usual suspects along the way -

mapped drives - deleted.
saved usernames/passwords - none use this account.
terminal server sessions - none.
logins elsewhere - none.

The only area of oddity is that the machine account is in the local
domain of our development team, whereas the users accounts are in the
main company domain. I have read of this being an issue with Vista,
can anyone confirm?

MIS have moved my machine account into the company doomain, but as I
left work today, my account was still locked out.

Any ideas?

Linux zealots need not reply (not that this will stop any of you
mannerless nerks, of course).
