Shutdown TFS

The TFS contains many web services and some windows services.
You can use the TFSServiceControl command to stop or start all of the services and application pools Visual Studio Team Foundation Server uses. For example, you use this command when backing up or restoring databases, or when you are moving your deployment from one machine to another.

TFSServiceControl [quiesce|unquiesce]

unquiesce	Starts or restarts all of the services, application pools, and operations in your deployment of Team Foundation Server. This is required to return your server to operation after you run the command with the quiesce option.
