I have a user that it appears put the wrong password in. She said she didn't. However, it keeps saying account is locked out. I go into the server and uncheck the lockout button, hit apply and ok. Then if I immediatly go back into the profile it is locked out again whether I tried to login as her or not.

It sounds like some service or schedule task is set to use the old credentials - check.

1. I cleared the security log and then immediately hit refresh. Two seperate accounts had already tried to login and fail over 100 times.

2. How do I check for services that may be using a old password?

3. Also, another strange thing is that the two accounts that keep doing this are logging onto two Vostro machines that we just formatted and reinstalled. They had Vista, we formatted and put XP Pro on them.

use this script - I can't remember where I got if from - but it works

strComputer = ""
Set objWMIService = GetObject  ("winmgmts:\\" & strComputer & "\root\cimv2")
Set colServices = objWMIService.ExecQuery ("Select * From Win32_Service")

For Each objService in colServices
    Wscript.Echo objService.Name, objService.StartName
Next

When I run the script I get an error. I am sure I am doing something wrong. Do I have to change that script in anyway?
