I recently reformatted my laptop, which meant of course that I had to reconfigure Vista's VPN client to allow me to access my home network (I connect directly to the router as an endpoint).
I can ping the router without a problem, and I set up the client exactly the same as I previously had (to my knowledge), but I get the following error when I try to connect:
"Error 809: The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g, firewalls, NAT, routers, etc) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem."
What's most odd to me is that I am connecting using the same settings as before, using the same internet connection as before (ie, no new/different hardware). I've even tried turning Windows Firewall off altogether on my client computer, but to no avail. Any help would be much appreciated. Thanks
Edit: One difference in the setup of my laptop: it is now on a domain where before it was on a workgroup. That being said, I am a domain admin, and the connection fails with the same error whether I am logged in as a local user or domain user.
Further edit: I tried connecting from another Vista client NOT on the domain. Also without success (same 809 error)
Edit: I tried the same connection from the LAN and got the following error: "Error 789: The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer." I did get an error log, but it's positively huge. If anyone can tell me what to pull from it, I would gladly post it up.
I will also post screenshots of my router setup.
