CAUSE

This behavior may occur if either of the following conditions exist:
  • There is a corrupted message in the Simple Mail Transfer Protocol (SMTP) queue. To verify whether this condition exists, follow these steps:
    1. Locate the Queue folder under Exchsrvr\Mailroot\vsi 1.
    2. Rename the Vsi 1 folder.
    3. Create a new Vsi 1 folder.
    4. Restart the IIS Admin service.

      Note The procedure in 317678 is also effective for Exchange 2003.
    5. Restart the Exchange services.
  • The Microsoft Internet Information Services (IIS) metabase becomes corrupted and causes the messaging protocol services to fail.

RESOLUTION

To resolve this issue, use one of the following methods, depending on your situation.

There is a corrupted message in the SMTP queue

Create a new Queue folder. To do so, rename the Queue folder to Queue_old, and then restart the IIS Admin service and the other Exchange services.

Important In a clustered Exchange environment, take the System Attendant Resource offline, restart the IIS Admin service, and then bring all the other Exchange resources online.

The IIS metabase is corrupted

Restore a version of the IIS metabase that is not corrupted. By default, metabase backup files are located in the %SystemRoot%\System32\Inetsrv\MetaBack directory. For additional information about how to restore the IIS metabase, click the following article numbers to view the articles in the Microsoft Knowledge Base:

302573 HOW TO: Back up and restore IIS

If no IIS metabase backup file exists, you must reinstall IIS on the Exchange computer. To do this, follow these steps:
  1. Open the services item in Control Panel, and then disable all Exchange-related services.
  2. Remove the Microsoft Windows component Internet Information Services (IIS) in Add/Remove Programs.

    Important If this is a clustered server, do not remove the shared components when you remove IIS. Removing shared components on a clustered server will render the cluster unusable.
  3. Remove the Metabase.bin file from the %systemroot%\system32\inetsrv folder. (This action may already be performed by the Windows Component Wizard.)
  4. Restart the server.
  5. Reinstall IIS in Add/Remove Programs.

    Note Make sure that you click Details and enable both the SMTP and NNTP services.
  6. Reinstall any previously installed Windows 2000 service pack. (You can skip this step if you have the service pack files available and the wizard does not prompt you for your Microsoft Windows 2000 CD-ROM.)
  7. Install Exchange again by using the Reinstall option.
  8. Restart the server.
  9. Reinstall any previously installed Exchange service pack.
  10. Mount the databases by using the Exchange System Manager.

MORE INFORMATION

The metabase is where IIS stores its configuration settings. Exchange 2000 uses both IIS and its metabase extensively for Outlook Web Access (OWA) and Routing and for the protocol services such as SMTP, POP3, and Internet Message Access Protocol 4 (IMAP4). It is suggested that you back up the metabase regularly as part of a system state backup or from the IIS administration tool.

Metabase corruption may occur for a variety of reasons, including the following:
  • Antivirus software scanning the %systemroot%\system32\inetsrv\metabase.bin file
  • Iisadmin.exe process stopped or killed unexpectedly
  • Unsupported editing of the metabase
  • Disk corruption or other hardware failures
