NNTP: Feed Postings Rejected Due to Missing Header

The information in this article applies to:

• Microsoft Commercial Internet Server version 1.0

SYMPTOMS

The Internet News Service (INS) may fail to post feeds to hub net news servers such as UUNET.

CAUSE

Hub net news servers, such as UUNET, now reject post feeds that do not include the NNTP-Posting-Host header. INS 1.0 does not include the NNTP-Posting-Host header.

RESOLUTION

Apply the fix referenced below, or wait for the next Service Pack. With the fix applied, the Nntpsvc.dll file is modified to include the NNTP-Posting-Host header. After you apply the fix, edit the following registry value to enable the NNTP-Posting-Host header:

      HKLM\System\CurrentControlSet\Services\Nntpsvc\Parameters\
   EnableNNTPPostingHost
   Type: Reg_DWORD
   Values: 0, 1
   
   NOTE: Must be set to 1 to force the server to generate NNTP 
   Posting Host headers.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Commercial Internet System version 1.0. A supported fix is now available, but has not been not fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix.
