SYMPTOMS
When you use the Microsoft Web Posting Acceptor in conjunction with the Microsoft HTTP Post RFC1867 Update for Microsoft Internet Explorer version 3.02, and the Microsoft Distributed Password Authentication (DPA) engine from Microsoft Commercial Internet System (MCIS) Membership Server, you may get one of the following error messages:

The parameter is incorrect.

-OR-

The Web Server is not responding or returned an unrecognized response.



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."



STATUS
Microsoft has confirmed this to be a problem in Microsoft Commercial Internet System version 1.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Commercial Internet System version 1.0. For information on obtaining the Service Pack, query on the following article in the Microsoft Knowledge Base:
