I need some help with our VPN solution, if you would be so kind :)
The full error message is
Remote Access error 789 - The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer
This only happens on one single users PC, and only when he is on his home network. No other clients is having issues.
I've tried to change the network profile from
Private. Did not help. I've also tried to change it to
Domain network, and that didn't help either.
We've got Symantec Antivirus on all machines, but again, there hasn't been any troubles like this on ANY other client.
The firewall SEEMS to be turned off when on
Domain network, but not on
Public. But this is controlled by the antivirus.
I haven't got immediate access to his router, and would prefer if this could be leaved "untouched"
The connection is a L2TP/IPsec, requires encryption, with a Pre-shared key. The clients use a batch, which is using rasdial to connect.
The server itself, is a Meraki firewall.
Please, ask any questions if you have any.
