There have been reports of a "Failed to initialize connection subsystem” error received while using Cisco AnyConnect to establish a virtual private network. The errors began with the February 2015 Microsoft security patch.
Microsoft has released a "fixit" to correct the regression in the February 10, 2015 patch. The fixit is accessible by following these instructions.
