RE: Cannot create a VPN connection using PPTP from 2003 Server

I found the following post on the Internet that describes how to re-install
miniports on Windows Server 2003 using devcon:
http://www.daniweb.com/forums/thread18016.html.

Cutting to the chase the steps are:

1. Download devcon.exe from some Microsoft site. You can google for it.

2. Open netrasa.inf in c:\windows\inf (c:\winnt\inf on win2k I guess)

3. Look for the section [Msft.NTx86]

4. In the DeviceID column, you can see the installable devices.

5. Run this command to install the WAN Miniport (PPTP):
devcon.exe install c:\windows\inf\netrasa.inf MS_PptpMiniport

6. You can install the other devices similarly. I think you will need
MS_L2tpMiniport, MS_PtiMiniport, MS_NdisWanIp, MS_PppoeMiniport additionally

Doing this addressed the '609: A device type was specified that does not
exist' issue, but now a different error has popped up.

I now get the following: TCP/IP CP reported error 31: A device attached to
the system is not functioning.

If I pass a bad username or password the connection asks for the correct
credentials so it looks like the PPTP connection is being established, but
not completed.

I found this MSKB article and tried it, but still no joy:

This is a registry change, but no reboot was specified. Is a re-boot
required? Anyone have any other ideas?

Thanks

I have a Windows 2003 Server machine that periodically 'reaches out' to
another server on the Internet by creating a VPN connection. The
connection uses PPTP and has been running fine until recently. When I
manually try to connect using PPTP I receive error 609: A device type was
specified that does not exist. Using L2TP returns the standard '...could not
establish connection...' error. This is expected since the remote machine is
not configured for L2TP.

Intenet connectivity is OK. Can ping out. Web sites on this server can be
reached from outside the firewall.

Other machines on the LAN execute the same process OK.

Device Manager on the problem box looks to have the WAN Miniport (PPTP)
driver installed OK.

Is this a case where the WAN Minport (PPTP) device needs to be re-installed?
