An application pool is not configured correctly

The information in this article applies to:

The Best Practices Analyzer tool for Team Foundation Server checks the configuration of the application pools in the following table:

Visual Studio 2005 Team Foundation Server	Visual Studio Team System 2008 Team Foundation Server
ReportServer	ReportServer Note You manage ReportServer in Internet Information Services ( IIS ) for SQL Server 2005 but not for SQL Server 2008.
TFS AppPool	Team Foundation Server Application Pool
TFSWSSADMIN	SharePoint Central Administration v3
TFSWSS	DefaultAppPool

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

Application Pool Identity is misconfigured

The identity of the ReportServer application pool should be set to Network Service. For all other application pools, the identity should be set to the TFSService service account, which is the account that you specified when you installed Team Foundation Server.
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 "Configuring Rapid-Fail Protection in IIS 6.0 (IIS 6.0)" in the Windows Server 2003 TechCenter on the Microsoft Web site.
Application Pool AutoStart is disabled

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

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