W2K & Access problem

I have the problem with a server, or maybe it isn’t the
server.

The client runs an access database with an asp HTML front end. It
generates work sheets which they email to the work force. However out
of the blue when you click on send page in explorer we get the
error. “Can’t send this type of page as mail, send shortcut instead.” I need this to work, Thanks in advance for any help
