Re: WAN Miniport (SSTP) - missing driver
I had this problem in Vista recently.
I used netcfg and devcon to resolve it. Netcfg is shipped with windows. Devcon needs to be downloaded from:
http://support.microsoft.com/kb/311272/en-us
I removed and readded the device with the warning sign. These are special devices for VPN links, etc. Device Manager cannot repair them directly. You may want try just adding the device back without removing it first.
To remove:
netcfg -e -u ms_ndiswanip
To add:
devcon install c:\windows\inf\netrasa.inf ms_ndiswanip
If you get a failure message in devcon, reboot and let the bootup process try to finish the install. Let it run to completion, it takes a couple of minutes. I had to do this. Devcon seems to fail adding the drivers to the device node when Windows is running.
Both of these commands are run from the cmd prompt. Copying devcon.exe to a convenient directory like c:\users\<your ID> first is helpful.
If your device has a different name substitute it above. You may want to check netrasa.inf with notepad or wordpad first to make sure it is part of this definition file. Most likely it is.
MSDN or TechNet have writeups on what MINIPORTS are used for in more detail.
Correct Problem Definition is 50% of the solution ...
