It's planned fix problem 2013 vs VPN in Patch C. But due to the fact that we cannot reproduce this problem in test lab we need your help in reproduction and providing info.
At first, those who can reproduce this problem check next cases:
1. Disabe KIS Autostart, reboot and check VPN.
2. Deinstall Kaspersky NDIS Filter, reboot and check VPN.
3. In registry disable kltdi (set value '4' in key 'Start'), reboot and check VPN.
We suppose that problem is reproduced with L2TP VPN.
1. For removing NDIS Filter in Network Connection properties select Kaspersky NDIS Filter and press "Delete".
2. Key kltdi is here: тут HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\kltdi
