vpn connection  does not connect

Posted on 2007-03-19
Last Modified: 2010-04-18
i have 3 DC's and 3 member servers, all working properly. Recentely, the remote access serivce (VPN) stopped working. I reset up the Routing and remote access on one of the dc,and 2 additional member servers with the same results.

The story is like this:
i am trying internally,which means that i do not have to worry about firewalls and routers. I can not connect from a workstation to the remote access service for any user who is granted  permissions to connect. But, i can connect with the same user account from any server or member server. no firewall is enabled at all. If i try to connect from a workstation on the same network, it just says connecting and that it it, then it quits. on the same worksation , i go to command prompt, and type netstat -a, and it shows me that it did established a connection to the remote access server. I tried everything, remote access policy dhcp relay agent with no luck. i am doing pptp. nothing special, and i am going with the default when i setup the routing and remote access server.
Any ideas

As a rule you cannot test this using your External/WAN/Public IP from the same site. You are asking the router to do a 'U'-turn, which most cannot do. Have you tried connecting from off site? or are you using and internal address on the RRAS server as a test ?

You might also want to review the configuration at:
Server 2003 configuration:
Windows XP client configuration:
Is the port forwarding on the router still the same, or has any of the IP addressing changed?

Thanks for the reply

I am not asking the router to do U turn, i am just entering the ip address of the RAS server while i am on site , i am not going out at all. If i can connect internally, i can manage the forwarding ports on the router.
My RAS Ip address is, my workstation is, on the workstation my VPN connection is set to contact to connect to the VPN.
I did try it from outside and on the router i have the 1723, 47 port forwarded to, it used to be working right until 2 weeks ago.

There is a security feature in the VPN client that blocks local connections, to protect the office/remote network. In a single server environment this should not affect your ability to connect to the RRAS server, but in the multi-server environment you have, I am not sure of the consequences when connecting locally. For example it could block access to your DC or DNS server. Perhaps try disabling as a test. I am "grasping at straws" but if you wish to do so, on the client/connecting PC, go to:
control panel | network connections | right click on the VPN/Virtual adapter and choose properties | Networking | TCP/IP -properties | Advanced | General | un-check  "Use default gateway on remote network"
SharePoint Admin?

I did that too with no success. I narrowed it down to policy issues, but i tried all kind policy setting for the users and still the same thing.
Thanks for the input Robwill

Any idea what "policy issues" ? Shouldn't have to enable/disable any polices within RRAS, IAS, or group policy to enable a connection. They are more for restricting access once configured. The only one that would need to be configured is to allow access. Usually this is set in the user's profile in active directory under dial-in. However, if it were set to disabled you would get a an authentication error when connecting.
