Add the service account for Team Foundation Server to the report server
If the report server and Team Foundation Server are not on the same server, you must add the name of the service account that you will use for Team Foundation Server to the Content Manager group on the report server. This step is done automatically during TFS setup if the report server is installed on TFS.
If you are using Network Service for the TFS service account, you must add the machine name of the server that is running TFS instead of Network Service. The machine name is the server name followed by the $ symbol. For example, Domain\ServerName$.
For more information about service accounts, see Accounts required for installation of Team Foundation Server.
To perform this procedure, you must be a member of the Administrators security group on the report server.
