OpenVPN Support Forum

Hi

I have installed OpenVPN client and server 2.3.4 on my Windows 7 32 Bit Enterprise edition systems. I have uninstalled the default TAP Driver and installed the one which I have built using Python script ( note no code changes been done). When I connect the OpenVPN client to the server I am observing frequent BSOD on NDIS.SYS with the below signatures. I have tried with previous version of OpenVPN and observed the same errors. Kindly guide me what could be the issue. I am planning to build TAP Driver with WIN8.1 WDK.

If Driver verifier is disabled I am not observing BSOD. But Driver verifier is enabled for TAP Driver automatically.

Hi,

something in the build of your tap driver went wrong - which is why it's crashing your system (blue screen).

Nobody will be able to answer *what* went wrong, though, I'm afraid - none of the developers build drivers on 8.1, we use old and trusted build systems (my TAP driver extentions have been done on WinXP, I think Samuli builds the official drivers on Win7). Since the old NDIS version is deprecated by Microsoft, it might well be that there is something in the 8.1 WDK that just breaks our driver.

Since we have a new NDIS6 driver - see https://github.com/OpenVPN/tap-windows6 - which uses the up-to-date API, it doesn't seem useful to invest time to debug why the old driver does not bild on Win8.1

What are you trying to achieve anyway? I'm a bit curious, because building the TAP driver is so much hassle that nobody does it without having a really good reason.

Hi Gert,

Thanks for your reply.

we would like to enable NDIS630 and NDIS640 for WIN8 and WIN8.1 respectively. The current TAP Driver supports only NDIS61.

Hence we are building TAP driver with WIN8.1 WDK.

Thank You,

Hi,

i had the same problems, Windows 7 64 bit and Asus Mainboard with Realtek chip, dont know if this matter. Anyhow after playing around with my G DATA antivirus and firewall it looks like the problem is somewhere else. Then I read this thread about this TAP Driver and take a look at the network connection using the TAP network adapter, and finally I found the problem in my case. Open the properties of the network connection using the TAP network adapter, and remove the unneeded ticks of the elements that this connection will use, like in my case from Shrew Soft, VMWare, Virtual-PC, and finally AVM VPN. After that no blue screens anymore.

Hope could help somebody with that.
