sbs 2003 one user account keeps getting locked out instantly

i have a sbs2003 domain.  one of my users just started getting locked out of her account instantly.  if you go into active directory, and unlock her account, then go back in, the same thing happens.  i have checked over her machine and there are no viruses?

i even turned that machine off and it is still happening.

Account Lockout (Event ID: 539) comes up like 20 times the same second every few minutes?

any ideas?

Wonder if any services are set with that users details..

Best to work out if it is on that machine or not, have you the security event logs for the failed logins?

Did the user recently changed the password? If the user is using a domain account, see if your domain controller has event id 644.This event should show you where there account was locked from which machine. May be the user have logged on to another machine or server with old password,  or have task or mapping using the old credential.

it was a vista home machine that was on the network and had a shared drive to the server the user had put in her username/password for that person.
