Vista locking network account

[Muad' Dib]

Our network has an Account lockout policy of 6 incorrect tries before
the account is locked out. I have two machines I use on the network.
One a box that I dual boot between XP (Primary) and vista ultimate(<-
I'm evaluating), the second an XP SP2 box that I use to connect to
remote database via Remote Desktop. In addition to the account lockout
policy, all of our machines will automatically lock the desktop if the
machine is idle for 15 minutes. The network is running Windows 2000
advanced Server on the PDC with Active Directory.

Here's my issue:

When working in my Vista install, If I'm logged into my remote XP
machine via RDC and the screen locks because of inactivity, Vista
somehow locks my network account. Even though there have been no
incorrect login attempts. When I come back to the machine to continue
my session, Vista informs me that the account is locked. I then have
to log onto the pdc and unlock the account through Active Directory.

This issue does not occur when booted into the primary XP OS on my
main machine.

I don't know if it is an issue with cached credentials, or some
difference in authentication schemes that is charging my network
account with multiple login attempts when I attempt to reconnect.

Can anyone point me in the right directions with this?

Lockout problem solved:

This issue was between Outlook 2007 and our network DC. Our office
uses a hosted Exchange provider. Outlook 2007 assumed that my email
account credentials were the same as my network credentials. Each time
I synchronized my inbox, Outlook was sending my email account
credentials to our PDC. It was this behavior that was violating the
account password/ lockout policy on our PDC. Once we figured out that
it was Outlook 2007, we were able to correct the issue.

So if you run into the same thing, check Outlook 2007.
