CAUSE

The error messages in the "Symptoms" section of this article occur if the Mfc42.dll file is missing or corrupted.

WORKAROUND

To work around 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

Make sure that the Add-ins subfolder is shared.

NOTE: You may need to check all of the drives for the drive that contains 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. In Windows Explorer, click the Exchsrvr\Add-ins subfolder.
  2. Right-click the subfolder, and then click Sharing.
  3. In the Add-ins Properties dialog box, click Share As. Make sure that the Share name and Comment boxes contain the following information:

    Share name: Add-ins

    Comment: "Access to EDK objects" (with the quotation marks)

  4. Click Permissions. Make sure that the Access through share permissions dialog box has the following permissions set:

    Everyone (which is a global group - with the globe icon) as Read
    Exchange Server service account name (individual icon) as Full Control
    Local administrators (local group icon) as Full Control

  5. Click OK.
  6. Click Apply, and then click OK.
This permission may be turned off during a service pack update or a reinstallation, which can cause this problem.
