CAUSE
This problem may occur if Exchange 2000 tries to use custom sinks that were previously installed and are no longer used or available.

{83D5BC59-B6C8-4B77-88B0-B7CA8F3BA1AC}

</li> Quit Meta Edit, and then restart SMTP services.</li></ol>

Test to determine if the issue is resolved. If the issue is not resolved, complete the steps in the &quot;You Are Not Using GFI Mail Essentials Version 8.0 or 9.0&quot; section of this article.

You Are Not Using GFI MailEssentials Version 8.0 or 9.0
You must rebuild the Exchange 2000 installation. To do so, remove and reinstall Internet Information Server (IIS). This removes the third-party event sinks that have been installed in SMTP. This operation can take as little as 30 minutes or as long as one hour to complete depending on the performance of the server. This is a non-destructive operation except to the metabase and to any outbound messages that are currently queued. If you have Web pages that are located on this server, Microsoft highly recommends that you back up these Web pages and the server before you perform the resolution.

Remove IIS
<ol> Click Start, click Control Panel, and then double-click Add/Remove Programs.</li> Click Add/Remove Windows Components, and then click to clear the Internet Information Services (IIS) check box.

To complete the wizard, follow the prompts.</li> Verify that the Metabase.bin file has been removed from the system by locating the following file:

\winnt\system32\inetsrv

If the Metabase.bin file exists, delete it.</li></ol>

Reinstall IIS

 * 1) Click Start, and then click Control Panel.
 * 2) Double-click Add/Remove Programs, and then click Add/Remove Windows Components.
 * 3) Click the Internet Information Services (IIS) check box to enable IIS.
 * 4) Click Details, and then click both SMTP and NNTP for Exchange.

To complete the wizard, follow the prompts.

Rebuild the Exchange 2000 server

 * 1) Re-apply the Microsoft Windows 2000 Service Pack 3 (SP3). If you are prompted to do so, restart the server.
 * 2) Insert the Exchange 2000 Server installation CD, and then start the Setup program.
 * 3) Click the Reinstall option. This overwrites the current Exchange 2000 core files but does not modify or replace the Exchange 2000 databases.
 * 4) During the reinstallation, click Yes to overwrite the current files.
 * 5) Re-apply Exchange 2000 Server Service Pack 3 (SP3).

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

MORE INFORMATION
In some scenarios, the sink bindings may exist in the Exchange 2000 metabase but the sink is not correctly registered in the registry. When this behavior occurs, the SMTP protocol does not create the sink when it tries to process the “MAIL FROM&quot; command. Therefore, Exchange 2000 drops the connection, and the outgoing mail is not processed.

This issue may occur when a third party program, for example GFI MailEssentials, is installed and then incorrectly or incompletely removed. GFI MailEssentials contains an add-on named Mail Security. Mail Security installs an outbound SMTP sink that verifies the validity of the sender address. If improperly removed, the sink may remain although the sink is no longer correctly registered. When the &quot;MAIL FROM&quot; command is initiated by Exchange 2000, the sink fails and Exchange 2000 drops the connection.
