SYMPTOMS
Large files fail when posted to Microsoft Posting Acceptor 1.0 by Internet Explorer (IE) 4.0.



CAUSE
Internet Explorer 4.0 will close a connection with an Internet Information Server computer upon an HTTP 401 response. An open connection is required to succeed with NTLM authentication, which is also required to upload via Posting Acceptor. If you are uploading a file larger than 48 KB, the message must be split into multiple packets to be processed by Posting Acceptor. Authentication information is also split over the packets. Between packets, a 401 response will be sent back to the client before NTLM succeeds, thus causing IE 4.0 to fail.



RESOLUTION
This problem has been corrected in Microsoft Posting Acceptor 1.01, which is available as part of the Windows NT 4.0 Option Pack, available at http://www.microsoft.com/iis.



STATUS
Microsoft has confirmed this to be a bug in Microsoft Site Server version 2.0. This bug has been corrected in Microsoft Posting Acceptor 1.01.
