If I did not send you here personally and give you the info below:
<public IP> is the internet facing IP address of your VPN server
<username> is your username on your domain
<domain> is the FQDN of your local domain
Great! So here is how to setup a PPTP VPN on Windows 7
1. Click on the start menu and in the “Search programs and files” box, type: VPN. In the search results above, “Set up a virtual private network (VPN) connection” should conveniently be selected so just press enter to start the wizard.
2. On the first page, enter your <public IP>, give your connection a name if you’d like and check the box “Don’t connect now; just set it up so I can connect later,” then click “Next”
3. Enter your username and if you’d like, enter your password and check the box to save. You can typically leave the domain field blank unless you have multiple domains. In which case, enter your domain’s NetBIOS name here, then click “Create”
4. On the “Connection is ready to use” page, just click “Close,” we have a few more settings to tweak!
5. Go back to the handy start menu “Search programs and files” box, and this time type: Network Connections. This time the first, highlighted result should be “View Network Connections” – so go ahead and hit enter to open your network connections.
6. On the network connections page, right-click the network connection you just created and then click on “Properties”. The connection will be called “VPN Connection” if you did not change it’s name in step 2.
7. On the network properties page, first click the “Security” tab, then drop down the “Type of VPN:” and select “Point to Point Tunneling Protocol (PPTP)”
8. Next click on the “Networking” tab, un-check “Internet Protocol Version 6 (TCP/IPv6)”, then click on “Internet Protocol Version 4 (TCP/IPv4) once to highlight it, and then “Properties”
9. On the property page here, click “Advanced”
10. On the first “IP Settings” tab, un-check the “Use default gateway on remote network” box. That way your computer will still access the internet directly when the VPN is connected, instead of sending all the internet traffic through the office network.
11. Now click on the DNS tab and enter your local domain name, this will help your computer find other computers and resources on your office network.
12. Finally click OK on all the screens until you get back to the Network Connections window. For convenience, you can right-click on your VPN connection and then click “Create shortcut” to add a shortcut to your desktop. (Click OK in the box that pops up asking if you want to put the shortcut on the desktop)
To connect to your VPN, just double click the shortcut on your desktop that you conveniently made. Enter your password if you didn’t choose to save it in step 3 and hit the “Connect” button.
The VPN will automatically disconnect if your computer disconnects from the internet or you shut it down / put it to sleep. If you’d like to manually disconnect. You can also do so by double-clicking on your icon and then clicking the disconnect button. (Or simply by right-clicking the icon and selecting disconnect)
