  • Microsoft Exchange Active Server Components 5.0

This article was previously published under Q172780


When you try to attach a file to a message using the Web client, the following message may be displayed if the computer running Internet Information Server (IIS) is not an Exchange Server computer:

HTTP/1.0 500 Server Error (The specified module could not be found.)


The attachment update is not registered.


To resolve the error, apply Exchange 5.0 Service Pack 1 to the computer running IIS, even though Exchange Server is not installed on this computer.
