I have an ISA550W deployed at our office locations. For remote access I am testing AnyConnect v3.1.05187. The laptops I'm testing on have Windows 8.1 Pro Update with all of the latest patches as of this post.
I read the release notes and as a consequence made sure WinPcap is not installed and the service non-existent.
I have run the MicrosoftFixit25005.
When I installed AnyConnect I unchecked the options for "Diagnostic and Reporting Tool", "Network Access Manager", & "Web Security".
Here is the problem; upon initial install it works flawlessly even without a reboot after running the installer. BUT if the OS is rebooted, it gives the following error: "The service provider in your current location is restricting access to the internet. You need to log on with the service provider before you can establish a VPN session. You can try this by visiting any website with your browser."
Now I can confirm that sometimes it takes a couple reboots or even until the next day for it to be broken. But all I have to do is uninstall everything, reinstall it and it works, all with no reboot after uninstall or reinstall.
So why does this thing just decide to break its self?
Anyone have any ideas? This is a major pain to everyone in our company that works remotely.
Perhaps someone could even just walk me thru how to produce a log to post here that may help, although I doubt it since I can't predict on which reboot it will break.
Surely someone else has had this issue or there is a known resolution for it? Please help!
