    WAN Miniport L2TP / IKEv2 Drivers Locking up


    Hi all,


    We have a number of sites which have L2TP / IKEv2 VPNs configured (various server/router hardware and configurations). In all cases though we use the Windows 10 in-built vpn client to connect and all are configured with pre-shared keys and typically RADIUS authentication linked to a Windows NAP server.


    For a large number (if not all) of our clients we regularly see the WAN Miniport drivers locking up and you have to either logout/login or manually restart the drivers in device manager to get them going again. These clients all use different versions of Windows 10 and different hardware configurations but the problem is always the same on each.


    The VPN client will usually get as far as "verifying username / password" and not get any further. In the event log you will see different RAS errors, usually 79 I think it is or 89 (whichever the standard, couldn't connect error code is. when it connects successfully you also will sometimes find that the network connection on the client (via all adaptors) is completely broken after disconnecting the VPN and can only be fixed by disabling/enabled the WAN Miniport drivers.


    Anyone seen this before and know of a fix?


    Cheers,


    Olly
