vpn internally will not connect

the windows firewall is not on is it?

no, it is not

beside it does not excplain why i can connect from member servers and other dc's but not the workstations.

Here is a repeat fo my question, and i wish somebody can help me with that. Please


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
