netvmini.sys still not working on Windows 7 even after driver signing disabled ?! (Windows debug mode necessary for debug drivers ???)

[Skybuck Flying]

Hello,

I installed the netvmini.sys "debug/checked" driver on Windows 7 x64.

I learned how to deactive "driver signing enforcement" during boot of
Windows 7 x64.

Now I boot into Windows 7 and the virtual network adapters are present in
connection settings and such.

They have IPv4 and IPv6 bindings and such and local area network addresses.

I open the "test program". They ("Microsoft Virtual Ethernet Adapter") show
up in the list.

I try to sent "IOCTL"'s to them but it says:

"Failed read".
"Failed write".

I suspect this might be because I booted into "normal mode".

Maybe checked/debug drivers only work in "windows debug mode" ???

I shall now attempt to:

1. Boot Windows 7 x64 RTM in debug mode.

and

2. Disable driver signing.

and

3. Test again to see if this helped ?!

Bye,
Skybuck.

Ok,

This time I booted into "windows debug mode" with "driver signing disabled".

I used WinDbg to make sure that it was in windows debug mode.

I open the "netvmini" test program.

It lists a couple of network adapters and such...

And then I click Action->"ioctl to control device".

It says:

"Failed to open the control device: Microsoft Virtual Ethernet Adapter".

I wonder if this is maybe a problem with "dos symbolic links" ?

Maybe it can't find it ?

Second part of solution:

Test program must be "run as administrator".

Mystery solved see other post for more details.

Apperently the example contains no code for the ioctl...

It just does a "trace message"/dbgprint and a break.
