== SYMPTOMS ==<br />
<br />
When one of the core .dat files is missing or corrupted, the message transfer agent (MTA) does not start. The internal Mtacheck that the MTA runs on startup does not write the appropriate error message to the Mtacheck.log file. Instead of letting the user know that one or more of the .dat files are missing or corrupted, the following error is written to the Mtacheck.log file:<br />
<div class="indent"><br />
<br />
A fatal MTA database server error was encountered. Call Microsoft Product Support.<br />
<br />
<br />
</div><br />
<br />

<div class="resolution_section"><br />
<br />
== RESOLUTION ==<br />
<br />
Copy any missing .dat files from the Bootenv folder on the CD to the Mtadata Database folder. Compare the .dat files in the Mtadata folder to the following:<br />
<div class="indent"><br />
<br />
Db000001.dat through Db000009.dat<br /><br />
Db00000a.dat through Db00000f.dat<br /><br />
Db000010.dat through Db000019.dat<br /><br />
Db00001a.dat through Db00001f.dat<br /><br />
Db000020.dat through Db000026.dat<br />
<br />
<br />
</div><br />
Also, if the Db000001.dat file is 0 bytes, that file is most likely corrupted and you will need to restore it from backup. If there is no backup of the Db000001.dat file, it is likely that mail that has been secured to a queue will be lost. This is because this file is responsible for keeping track of which messages are secured to a particular queue.<br />

<br />
== STATUS ==<br />
<br />
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.<br />
<br />
</div><br />
<div class="moreinformation_section"><br />
<br />
== MORE INFORMATION ==<br />
<br />
You will also see an error with Event ID 2152 in the application log when the MTA will not start because of a problem with the .dat files<br />
