Changing TFS user account passwords

If you change the domaintfsservice and/or the domaintfsreports as you would expect your TFS server to stop, and it does. To get it back working you have to reset the passwords in:

• The various TFS AppPools on the frontend server need the new tfsservice password
• The datasource in ([frontendserver]/reports) on the reporting services need the new tfsreports password.

After that all should be OK
