SYMPTOMS

If you use the Microsoft Internet Information Server Management Console, you may notice that the Simple Mail Transfer Protocol (SMTP) virtual server has not started. If you try to start the Internet Information Services (IIS) Manager, also called the Internet Services Manager (ISM), you receive the following error message after a delay:
The service did not respond to the start or control request in a timely fashion.
Additionally, in the ISM status column for the SMTP virtual server, you may receive the following status message:
The requested control is not valid for this service.
Note On a Microsoft Windows Server 2003-based computer that has IIS 6.0 installed, you may also receive the following error message:
The service has returned a service specific error code.

CAUSE

The registry entries that are used by the SMTP virtual server may be missing or corrupted.

MORE INFORMATION

We strongly recommend that all users upgrade to IIS 6.0 installed on a Windows Server 2003-based computer. IIS 6.0 significantly helps increase Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:
