Trying to connection to a windows VPN

I'm new to VPNs in general and I'd firgue learning how to do this on ubuntu would be a great start I'm using pptd from the network manager. Whenever I try and connect to the vpn that's using Window's Server, I get "authenication required" and it doesn't connect. Under the PPTP Advanced Options I have MSCHAP MSCHAPV2 checked as well as MPPE, and under security I have 128-bit slected. To get more information I checked the sys log and here is the information my system returning when I try and connect.

I tracked down my problem. It lied with the line

MS-CHAP authentication failed: E=649 No dialin permission 

I talked to my sys-admin and it turns out I didn't have the correct permissions to connect to the vpn on windows server side. There goes a couple of hours thinking something was wrong on my end when it wasn't
