ID: Q196924

The information in this article applies to:

SYMPTOMS

When trying to open the property pages for the Internet Mail Service, you may receive the error message, "Extension SMTP Could Not Be Loaded."


CAUSE

The Imcadmin.dll is causing a version conflict, and to correct the problem, you need to find the build number of the file (file properties, or the filever utility), and use that number for a raw mode entry change.


WORKAROUND

Do the following from the computer that is running the Exchange Server Administrator program:

  1. Map a drive to the Exchsrvr directory of the computer that has the Internet Mail Service installed on it.


  2. Using Windows NT Explorer, locate the Imcadmin.dll file in the following directory: Exchsrvr\Addins\Smtp\I386.


  3. Select the Imcadmin.dll file, and on the File menu, click Properties.


  4. Select the Version tab, and write down the file version reported here.


WARNING: Using the raw mode of the Exchange Server Administrator program (admin/r) incorrectly can cause serious problems that may require you to reinstall Microsoft Windows NT Server and/or Microsoft Exchange Server. Microsoft cannot guarantee that problems resulting from the incorrect use of raw mode can be solved. Use raw mode at your own risk.

  1. Start the Exchange Server Administrator in raw mode by typing the following at a command prompt:

    C:\Exchsrvr\Bin\Admin.exe /r


  2. Within the Administrator program connected to the Internet Mail Service computer, expand the Configuration container, and select Add-ins.


  3. In the right window, select Extension for Internet Mail Service I386.


  4. On the File menu, select Raw Properties.


  5. From the Attribute list, select File Version, and click Editor.


  6. Select File Version, and click OK.


  7. Change the build number to the build number you got from Windows NT Explorer.
