I am getting this error when I try to Post via Microsoft.XMLHTTP:


msxml3.dll error '800c0008'


The download of the specified resource has failed.

The error occurs when I do the Send. Here is the code:



set objHttp = CreateObject("Microsoft.XMLHTTP")
objHttp.open "POST", "https://www.paypal.com/cgi-bin/webscr", false
objHttp.Send IPN

I've spokent to PayPal and they insist the problem is on my side. I was using the same code with no errors for over 2 months. It just stopped working on 6/26/05. Was there a change to the environment or something? Any thoughts would be appreciated.
