I am trying to run NDIS 5.1 driver on Windows Vista. I am currently using a non-checked build of ndis.sys (if anyone knows where can I get a checked one - this will be a great help).

In WDK they say that no porting is needed and 5.1 must run on 6.0 with no problems at all. However (I am using Kernel Debugger) the DriverEntry() is called and then (on the same thread stack) DdriverUnload() instead of MiniportInitialise() is called...

Does anyone know what might be the problem?

Thanks,
Dmitry.
