2. Wan Miniport Driver Download

I had a user install an older version of SonicWall Netextender and it inavertantly broke the miniports. Under Device Manger the IKEv2, IP, IPv6, L2TP, Network Monitor, PPOE, PPTP and SSTP Miniports all showed with a yellow exclamation mark. (The miniports are typically hidden too, so if they aren't broken, they won't show up) This caused all attempts at establishing a VPN connect to not work. You can alway reinstall Windows but if the user/device is remote, as in my case, that may not be a viable solution. All it takes to fix them is uninstalling and re-installing the broken miniport. Unfortunately, they can't be uninstalled and re-installed like normal devices. After much Googlin', intuition and guessing I came upon this solution.

2 Steps total

Step 1: Uninstall the broken miniports

WAN -Miniport (L2TP) - download driver driver-category list As soon as you aim to take care of a given hassle that originates from the defective WAN -Miniport (L2TP) be aware that various other drivers sometimes have become damaged by the corrupt code, and therefore need bringing up-to-date also. WAN Miniport (IKEv2) - Driver Download Updating your drivers with Driver Alert can help your computer in a number of ways. From adding new functionality and improving performance, to fixing a major bug. Budget-oriented series of PC cases from Thermaltake has been replenished with two new models: Versa H23 and Versa H23 Window. The mere difference between the two enclosures is the availability of a side-faceted acrylic window in ‘Window’ version.

1) Open Device Manger (Right click on Computer and choose Manage -> Device Manger). Then in the View menu select 'Show hidden devices'.
2) Right click on the non-working miniport, choose “Update Driver”.
3) Choose “Browse my computer”.
4) In the next window, choose “Let me pick driver from a list”.
5) Uncheck “Show compatible hardware”. From the “Manufacturer” list, choose “Microsoft”, and from the “Network Adapter” list, choose “MAC Bridge Miniport”. (It can be any device the user is allowed to uninstall.)
6) Now you can delete the device that just turned into the “MAC Bridge Miniport” device.

After you have changed and deleted all of the broken devices, REBOOT. If you skip this step bad things can happen.

Step 2: Reinstall the miniports

Now the hard part. The miniports can not be installed like normal devices and are blocked by default. There are a couple of suggested methods of reinstalling them by commenting out the ExcludeFromSelect section in netrasa.inf. However, in my attempts this file is locked down by the system and there isn't an easy way to make them editable.

1) Download a current version of devcon.exe. Keep in mind the 32-bit version won’t work on 64-bit systems. Follow the steps outlined in “How to Obtain the Current Version of Device Console Utility (DevCon.exe)” http://social.technet.microsoft.com/wiki/contents/articles/182.aspx on Microsoft’s TechNet wiki to obtain the ISO. From there I used 7-zip to open the ISO. Go into the WDK folder and look for setuptools_fre_cab001.cab. Again drilling into the cab using 7-zip you will find a file called _devcon.exe_00000. Extract this file and rename it to devcon.exe.
2) Open a Command Prompt and cd to the directory where you extracted devcon.exe
3) For each miniport that you have previously uninstalled, execute the command outlined below. DO NOT run all of them or run the command twice, as that will create second version of the existing miniport, which can cause problems again. If you are curious about where the Hardware ID and inf name comes from, in device manager on a working system, right click the miniport -> Properties -> Details Tab -> in the Property drop down select Hardware Ids or Inf name to see.
If running the command reports “driver install” failure, don’t worry, it usually does. The only problem is when it complains about the inf file missing, or a missing class (in which case you most likely made a typo in the last part of the command).
◦IKEv2:

◦SSTP:

Once done REBOOT. For me the IKEv2 device still had a exclamation mark after reboot. For this run 'sc config RasAgileVpn start= demand' from a Command Prompt.

I hope this saves other people the few hours I spent in find the resolution to the missing or broken miniport maniacal problem. You man need to reinstall the VPN software and add any profiles.

  Hello and thank you for this procedure, I just tried the first step of your procedure on a Windows 8.1 Samsung laptop for a user that can't use any VPN, either Cisco or Microsoft, the miniport type I have selected isn't showing, would you have any suggestions? Vag com software free download.

  Thank you

  Was the first step successful. Meaning that it was there and following the first step allowed you to delete it? If that is the case then you need to re-add the miniport(s) that you deleted outlined in second step. If that is not the case it is a hidden device and you need to enable show hidden devices.
