Have you ever wanted to change the domain administrator password, but you were not sure if computer services were using the account?  Recently, a customer ran into this dilemma and asked for our assistance.  My first thought was to check the audit log on each individual server, but I realized after a few minutes that this would be no easy task.  Fortunately, after some research, I stumbled upon this fantastic PowerShell script written by Michael B. Smith and posted on his blog.  Michael's post can be found here: <a href="http://theessentialexchange.com/blogs/michael/archive/2008/02/29/finding-services-using-non-system-accounts-with-powershell.aspx">http://theessentialexchange.com/blogs/michael/archive/2008/02/29/finding-services-using-non-system-accounts-with-powershell.aspx</a>

The trick is typing out the servers you wish to scan into a text file, naming the file "listofcomputers.txt", and placing the text file in the same location as the PowerShell script.  Once ran, the script will go through your list one server at a time, and detail which services are not using "Local System".  The services using the domain administrator account will even be totaled towards the end of the output.
