MBS: Web Post Acceptor May Not Work with DPA Installed on Web Server

CAUSE

The "Parameter is incorrect" error message indicates that the Microsoft HTTP Post RFC1867 Update cannot read the Postinfo.asp file. The Microsoft Web Posting Acceptor works for the first post when the Uploadx.asp file is loaded.

The Microsoft HTTP Post RFC1867 Update reuses the connection that was authenticated with DPA on loading of the Uploadx.asp file. On a re- post, the Microsoft HTTP Post RFC1867 Update opens a new connection, attempting to authenticate the user, and gets an HTTP redirect to the Membership Broker System (MBS) troubleshooting page because the authentication failed. Internet Explorer then displays an error message saying, "The Web Server is not responding or returned an unrecognized response."
