List of Services by Service Account Name will list all Computers with a particular service account name. This report is useful prior to deleting a service account or changing its password because you can proactively see what services on which servers will be affected before making any updates.
Using the screenshot below as an example, we can see that there are only two services using the account GARTEK\sm2012adm. Given this data, we now know that if the account ID is deleted or the password is changed, we would also need to address these two services as part of this update. From this report, you can drill through to Computer Service Details.
