I am using a synology NAS that has a L2TP/Ipsec VPN server running. The NAS is located in a network with a FritzBox router.
Now I am in another network that is also established with a FritzBox router. From here I can connect to the VPN via debian and android. But on one of two Windows 10 machines it is not working.
And now I am curiouse, why the one windows 10 will not connect. To fix this one computer is my question in this post.
I have set up the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent with the value
The services are running:
IPsec Policy Agent and
IKE and AuthIP IPsec Keying Module
I checked the credentials (username, domain, password, ...) several times.
Also the preconfigured key is entered correctly.
No error code that I can follow.
The computer that it is not working on is a Surface Pro 4, newest updates from yesterday evening.
Some things that I tried (none of them had any effect on the problem):
- Going to the device manager -> networkadapter -> delete all
WAN Miniport-> action -> search for changed hardware
- disabeling the
Xbox Live-Networkservice(was not running in the first place)
- I tried to restart the
DHCP-Client, but permission denied with code
4. So I could not restart. Trying to fix this permission issue also did not work (more permissions in the registry and adding some extra users to the admin group like system and so on.). So I tried other things.
What am I missing? Why is this setup working on several windows 10 computers, but not on this one surface?
thanks and greetings
