XADM: Internet Mail Service Error with 5.5 Added to 4.0/5.0 Site (183171)

SYMPTOMS

After you add a computer running Exchange Server 5.5 to an Exchange 4.0 or Exchange 5.0 site, using the Administrator program from version 4.0 or 5.0, you cannot see all properties for the Internet Mail Service (Internet Mail Connector in 4.0). If you double-click on the Internet Mail Service, the following error message appears:

Extension SMTP could not be loaded. The specified Module could not be
found.

However, the Internet Mail Service can be administered using the Exchange Server 5.5 Administrator program.

CAUSE

During the installation of an Exchange Server 5.5 computer into the Exchange 4.0 or 5.0 site, not all libraries required for a static link for run-time are replicated over to the Exchange Server computers running 4.0 or 5.0, or to any computer running the Administrator program from version 4.0 or 5.0.

WORKAROUND

To work around this problem, do the following:

Copy two files from the Exchange Server version 5.5 CD: Mfc42.dll and Msvcrt.dll.
Insert those files into the winnt\system32 directory on the computers running the Exchange 4.0 or Exchange 5.0 Administrator program. Because the Msvcrt.dll file is a C-Runtime file used for certain operating system time functions, a file lock will be established at startup.
If the computer is using NTFS, you must perform a parallel installation of Windows NT (in other words, install Windows NT into another directory or partition on the same computer). Then copy over the files into their appropriate location. If you are using FAT, go to MS-DOS and copy over the files.
