At a customer of mine we recently had to do a full password reset of ALL of Active Directory. This included all user and service accounts, even the SharePoint ones. If you have EVER had to do this, you know that if you don't change the password in SharePoint a few minutes after the change in AD, you will be forced to manually change them across soo many places its not even funny. It turns out, we had to do a second password reset not long after the first one. It will become a commonplace thing that ALL passwords will be reset every couple of months and therefore, changing the passwords across all the farm servers (SharePoint, FAST and SQL Server) just ain't going to cut it.
Therefore, I wrote a PowerShell script to do it! It worked really well! It changes every single place one could imagine to have a username and password in your farm. I was going to post it, but decided that I would make a product out of it. If you would like to try out this gem, send me an email and I can send you a trial:
