I came across the below information in the ColdFusion forums that seems related to my MSXML problems. Are there any alternatives or patches to winhttp?

I've been able to isolate part of the timeout problem with ServerXMLHTTP as it pertains to the winhttp stack. Because ServerXMLHTTP uses winhttp and winsock to open and send data, when the server you're sending data TO does not respond or even does not exist, winsock and winhttp will timeout but NOT return anything to ColdFusion Server. This results in an open thread on ColdFusion that will eventually cause it to hang.
I've traced the winhttp stack with the winhttp 5.0 sdk and can see that timeout does occur:

Thank you,
