We have a 2008R2 Webserver with IIS 7 that we access from Navision Webservices using msxml3 automation. Everything is working correctly. We created a new 2012 server with IIS 8 and was forced to shutdown ssl and tls 1.0 (due to PCI compliance). When we run our Navision msxml automation routine in Windows 8 or 2012 server again everything works fine; however, when when we run it from Windows 7 or Windows server 2008 R2 we get the following error:
Microsoft Dynmics NAV Classic
This message is for C/AL programmers:
The call to member send failed. msxml3.dll returned the following message:
The connection with the server was terminated abnormally.

I've turned on tls 1.1 and tls 1.2 on the windows 7 box (and rebooted) but still get the same error.

The windows 7 system is using msxml3r.dll version 8.110.7601.18980 while the windows server 2012 server version is 8.110.9600.16384. Is there a way to make the automation routine to work with Windows 2008 R2 and 7? We have many clients that still run on earlier windows versions.
