CAUSE
The value of the following registry key in the HKEY_LOCAL_MACHINE subtree
System\CurrentControlSet\Services\MSExchangeMTA\Parameters\X500 DN
does not match the corresponding directory entry.
RESOLUTION
Check the value of the registry key, and edit it if necessary so that it
matches the corresponding registry key.
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall Windows NT. Microsoft cannot guarantee that
problems resulting from the incorrect use of Registry Editor can be
solved.
Use Registry Editor at your own risk.
- Start Registry Editor (Regedt32.exe).
- Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:
System\CurrentControlSet\Services\MSExchangeMTA\Parameters\X500 DN
- Check the VALUE for this key. The Organization [o=], Site [ou=], and
Server Directory names [cn=] must exactly match the properties of the
Organization, Site, and Server objects as displayed in Microsoft
Exchange Administrator program.
To see whether these objects match the value of the registry key:
a. Click on each of these objects in the left-hand pane of the
Microsoft
Exchange Server Administrator program.
b. On the File menu, click Properties. The Directory Name of each of
these objects should exactly match the corresponding attribute in
the
registry setting described above.
MORE INFORMATION
When the Microsoft Exchange MTA initializes, it checks the Distinguished
Name of the MTA object in the registry and verifies it is exactly the same
as the one stored in the Microsoft Exchange Directory.
