An error appears if one of the following conditions is true:

  • An application pool is not configured correctly

    The identity of all application pools should be set to the correspondingservice account that you specified when you installed Team Foundation Server (TFSService). For more information, see the following page on the Microsoft Web site: Service Accounts and Dependencies in Team Foundation Server.

  • An application pool is stopped

    The application pool should always be running. If you have a specified number of failures in a set time period, the application pool might stop as a result of the Enable rapid-fail protection setting. For more information, see the following page on the Microsoft Web site: Configuring Rapid-Fail Protection in IIS 6.0 (IIS 6.0).

  • AutoStart is disabled for an application pool

    If an application pool stops running, the AutoStart setting might get disabled. If you restart the application pool, you reset the AutoStart setting.

  • The "Maximum [Number of] Worker Processes" configured for an application pool is incorrect

    The maximum number of worker processes should be set to 1 for all application pools.

To resolve these issues, you must modify the configuration for the application pool that the error specifies.
