For example, if an Active Directory domain policy requires that all passwords expire periodically, you can update the password information for the service account in TFS when that password changes.
TFS stores a record of the name of the actual account that is used as its service account.
By changing the record, you can assign a different account to act as the service account. Whether you change the account, the password, or both, you stay synchronized with other components in your deployment.
If your deployment includes more than one application-tier server, you must perform this task on each server, or the account information will be out of synchronization.
To configure TFS to use a different account as the service account for Team Foundation, you can use either the administration console or the TFSConfig command-line utility.
Contact your network administrator if you encounter any proxy issues.
