I maintain a legacy website written in asp classic that uses the MSXML2.XMLHTTP.6.0 DLL heavily and today all of a sudden it is throwing an error advising it can’t find the specified DLL. I did a check and the DLL is there and is registered correctly on the server.
Does anyone know if this DLL is no longer supported in Windows?
I have now resolved this (for now). The issue was with one of our API providers not the dll. Here was their response:
"We found a cipher that is not vulnerable and still supported on win 2012. Could you please test if you have an issue connecting using Win2008? We could leave it enabled for a longer period."
Enabling this cipher is what fixed the issue.
