PPPoE Problem: unavailable - device missing

Monday, September 10, 2007 Posted by Ismail Habib 49 comments
Last week I tried to make a new PPPoE connection to my campus. I did it before and everything went fine, but not last week. I couldn't do the dial and when I saw the dial-up icon this not-so-funny-message under the dial-up icon: unavailable - device missing. I went crazy for sometimes before I found this solution:

1. Download devcon.exe from some Microsoft sites

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. Install the other devices similarly. (Probably you will need MS_L2tpMiniport, MS_PtiMiniport, MS_NdisWanIp, MS_PppoeMiniport additionally)

It worked. I didn't even bother to try to understand anything :P
