Hey guys I'm running into some PPTP VPN Issues with windows and my domain. I wanted to know if anyone was had any ideas.

So, we have a 2003/2008 hybrid domain and everything normally works fine. But recently I setup a VPN so users could access our phone system using DD-WRT & PPTP. Before connecting to the VPN they have zero problems on the domain but after connecting they sometimes get bad username / password errors accessing network resources. The users are getting access to the resources on the phone system they need.

If I disconnect from the VPN the problem remains, but if logout of the user account and back in everything is back to normal.

I turned off on the VPN Connection: Client for MS Network, File Sharing, and Use default gateway on remote network on the VPN connection. I'm also not providing DNS to the VPN.

Internal Network:
192.168.1.1
255.255.255.0

External VPN Network
10.0.0.1
255.255.0.0
