SYMPTOMS

If you remove an information service in Microsoft Exchange and then try to reinstall it, the information service may not appear when you click Services on the Tools menu and then click Add.

CAUSE

This behavior can occur if a dynamic-link library file (DLL) associated with the information service is missing.

RESOLUTION

To resolve this issue, use one of the following methods:

Copy the .DLL from the Exchange Server CD-ROM to the \<winroot\system for Windows 95 or Windows 3.x or \<winroot>\system32 for Windows NT.

-or-

For the Windows 95 additional service providers (including Microsoft Fax, Microsoft Mail, The Microsoft Network Online Service, or Internet Mail information service) extract each of the missing files from your original Windows 95 or Plus! for Windows 95 disks or CD-ROM to your Windows\System folder. For information about using the Extract tool, type "extract" at a command prompt, or see the following article in the Microsoft Knowledge Base:
129605 How to Extract Original Compressed Windows Files

For a listing of files associated with each information service, please see the More Information section of this article.

If you want to reinstall the CompuServe Mail information service, double-click the Setup.exe file in the Drivers\Other\Exchange\Compusrv folder on the Windows 95 CD-ROM.
