Domain account locked out repeatedly

Hi,

We have a Windows Server 2003 active directory domain, ISA server with VPN,
and one Windows Vista client. The Vista owner calls me every time he wants to
connect with VPN, and tells me that he cannot. Looking in Active Directory
shows me, that his domain user account is locked out. When I unlock the
account he is able to login. It seems that something (a service? office
2007?) does try to authenticate with wrong credentials, and locks his account
every time it can.

I have the default settings for the account lockout policy, threshold of 3,
and 0 for lockout duration.
This problem is really annoying so much, that I think about to tell him to
uninstall Vista and install XP again. The XP users don't have this problem at
all.

I've looked around in the web and found some other users that have the same
problem. But I found no solution for it.

I don't want to uninstall Vista. If anyone can help or has got an idea, this
would be really be appreciated!

Thank you!

To confirm it is Vista issue, create a temp ID to test. Please post back
with the result.
