When you start the Microsoft Exchange Server message transfer agent (MTA), the following error message may appear:

The dynamic link library Ecbios.dll could not be found in the specified

The Windows NT Application log shows the following error:

   Event ID: 9106
   Category: Field Engineering
   An internal MTA error occurred. The X.25 interface failed to initialize.
   Check to make sure the X.25 card is started. (14)

The MTA starts after the error and appears functional.


The above error means that during the MTA initialization it could not initialize the Eicon X.25 card.

This means that either the Eicon X.25 driver is not properly installed or there is a problem with the installed driver.


To resolve this problem:

  • Reinstall the Eicon driver and the WAN Services for Windows NT software.

This problem most often occurs after you perform an Exchange Server Disaster Recovery on a computer without first installing the Eicon software if the X.25 card was being used on an X.400 connector.
