XADM: Error Message: Extension SMTP Could Not Be Loaded

• Microsoft Exchange Server, versions 5.0, 5.5

SYMPTOMS

When you try to open the properties of the Internet Mail Service, the following error message may be displayed:

Extension SMTP Could Not Be Loaded.

CAUSE

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

WORKAROUND

Perform the following steps at the computer that is running the Exchange Server Administrator program to find the build number of the file:

1. Map a drive to the Exchsrvr folder of the computer on which the Internet Mail Service is installed.



2. In Windows NT Explorer, locate the Imcadmin.dll file in the following folder:




Exchsrvr\Addins\Smtp\I386

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



4. Click the Version tab, and write down the file version that is displayed here.

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




c:\exchsrvr\bin\admin.exe /r

2. In the Exchange Server Administrator program connected to the Internet Mail Service computer, click to expand the Configuration container, and then click Add-ins.



3. In the right pane of the window, click Extension for Internet Mail Service I386.



4. On the File menu, click Raw Properties.



5. In the Attribute list, click File Version, and then click Editor.



6. Click File Version, and then click OK.



7. Change the build number to the build number that you found in Windows NT Explorer.
