We are having issues with constraining web services to using secure protocols. Our web servers are dual NIC Windows 2008R2 with a dedicated NLB NIC and LAN NIC. The NLB NIC is showing the correct protocols and ciphers when tested on ssllabs but web services (which must use the LAN NIC) are trying to use deprecated protocols and the vendor site is refusing the connections.When I use any browser from the web server it shows TLS1.1 and 1.2 only. Since the web service is a on a site served by IIS7.5 it is actually a client but doesn't comply with Internet Options settings.
Any suggestions would be greatly appreciated.
