The information in this article applies to:

SYMPTOMS

When you attempt to view the Microsoft Exchange Server Internet Mail Service Properties in the Microsoft Exchange Server Administrator program, you may receive one of the following error messages:

Extension 'SMTP' could not be loaded.
The error 87 occurred while formatting windows NT error 182.
Microsoft Windows NT ID No 0xc00200b6
-or-
Extension 'SMTP' could not be loaded.
The specified module could not be found.
Microsoft Windows NT
ID no: 0xc002007e


CAUSE

The above error will occur if the file, Mfc42.dll, is missing or corrupted.


WORKAROUND

To correct this problem, copy the Mfc42.dll file from the Exchange Server CD to the SystemRoot\System32 subfolder of the computer running the Exchange Server Administrator program.

Additional Workaround

Check to make sure the Add-ins subfolder is shared.

NOTE: You may need to check all drives for the drive that has the shared folders under this subfolder. The standard shared subfolders in the Exchsrvr folder are: Add-ins, Address, Connect, RES, and Tracking.log

If the Add-ins subfolder is not shared, share it as follows:
  1. Use Explorer to select the Exchsrvr\Add-ins subfolder.


  2. Right-click the folder and click Sharing.


  3. In the Add-ins Properties dialog box, click Share As and it should read:


    4. Share name: Add-ins
    Comment: "Access to EDK objects" (with the quotation marks)
  4. Click Permissions. The Access through share permissions dialog box should have the following permissions set:


    5. Everyone (which is a global group - with the globe icon) as Read
    Exchange Service Account name (individual icon) as Full Control
    Local Administrators (local group icon) as Full Control
  5. Click OK.


  6. Click Apply and OK. The error should be cleared.


Sometimes this permission gets turned off during a service pack update or a reinstall, and can cause this error.
