Important This article contains information about editing the metabase. Before you edit the metabase, verify that you have a backup copy that you can restore if a problem occurs. For information about how to do this, see the "Configuration Backup/Restore" Help topic in Microsoft Management Console (MMC).
When you use Telnet to connect to the Simple Mail Transfer Protocol (SMTP) service of a Windows 2000-based server (regardless of whether it is running Exchange 2000), the following banner is displayed:
220 hostname.domain.com Microsoft ESMTP MAIL Service, Version: 5.0.2195.1600 ready at Thu, 30 Nov 2000 18:09:43 -0600
Warning If you edit the metabase incorrectly, you can cause serious problems that may require you to reinstall any product that uses the metabase. Microsoft cannot guarantee that problems that result if you incorrectly edit the metabase can be solved. Edit the metabase at your own risk.
Note Always back up the metabase before you edit it.
This may be an issue if you do not want the version of the SMTP service that is running on your server to be displayed. To remove the version information from the Windows 2000 SMTP banner, follow these steps:
NOTE: The fully qualified domain name (FQDN) (as it was entered in the SMTP service properties) and the date and time are still displayed. The following text is an example of modified banner:
