Windows 10 Cisco AnyConnect Issue

I’m running the publically available Windows 10 Technical Preview and have been having an issue connecting to my company’s VPN using the Cisco AnyConnect client. The error messages that come up are:

AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.


An unknown termination error has occurred in the client service.

After doing a bit of digging, I came across some logs in the AnyConnect logs (in the Windows Event Viewer), that looked like this:

Function: CNetInterface::GetGatewayAddress
File: .\Utility\NetInterface_win.cpp
Line: 190
Invoked Function: CNetInterface::GetIPAddrInfo
Return Code: -32571377 (0xFE0F000F)

They all had the same description: NETINTERFACE_ERROR_INTERFACE_NOT_AVAILABLE. Doing a quick Bing search led me to this article which included the following line:

Confirm that only one instance of the AnyConnect adapter appears in the Device Manager.

Well…I certainly hadn’t taken a look in Device Manager in quite a while, but when I did…guess what I found…a duplicate (and disabled) AnyConnect adapter.


Once I removed that extra disabled adapter, AnyConnect connected the first time through.

One more thing to keep in mind though…there is still the issue of extraneous characters in the DisplayName in the registry that I blogged about a couple of years ago related to Windows 8.
