Using TFSAdminUtil Command-line Tool to assign a new TFS Service Account

Team Foundation Server includes several services and service accounts that run on either the data-tier server, or the application-tier server, or both. Your actual services will vary, based on which features of Team Foundation you have installed on your data tier and application-tier servers. For example, if youusesfor a single-server setup, you will have both data-tier and application-tier services that run on the same server.

If you must reset the service account password for the Team Foundation Server, you must change the password for several services on the Team Foundation Server application-tier servers by using the TFSAdminUtil command-line utility. You can also use the TFSAdminUtil command-line utility to determine which services are running under a named account. The following table lists the service names, what service account they use, and what tier these services run on.
