Hi all,
I just wanted to give the community a heads up in regards to the latest February 2015 Microsoft patches.KB3023607 makes some AnyConnect clients give the "Failed to initialize connection subsystem" error. You can fix this here:

Also updated in the article:
This issue was introduced by KB# 3023607: Secure Channel cumulative update changes TLS protocol renegotiation and fallback behavior (https://support.microsoft.com/kb/3023607)
Included with Microsoft Security Bulletin MS15-009 – Critical Security Update for Internet Explorer (3034682)
This issue should also affect Windows 7 user with IE 11, but no reports of failure have been seen yet.”
