Hi,

Two days ago we change our server to upgrade a new one.

Since we change server, (same OS : Windows 2003 Web Edition), IPN paypal returns error 500. (In the old server still works fine)

The code error is :

msxml3.dll error '80072f7d'

An error occurred in the secure channel support

The code :

str = Request.Form & "&cmd=_notify-validate"

' post back to PayPal system to validate
set objHttp = Server.CreateObject("Msxml2.ServerXMLHTTP")
'objHttp.open "POST", "https://www.paypal.com/cgi-bin/webscr", false
objHttp.open "POST", "https://www.sandbox.paypal.com/cgi-bin/webscr ", false /NOW Working with paypal sandbox.

objHttp.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
objHttp.Send str <- Error

There is a server configuration problem, but i don't know hoy fix it.

Regards.
