Hi, I am working on NDIS driver development. I have successfully build the NDIS passthru driver sample source available in WinDDK. It is getting build and installed successfully on windows XP OS and i am able to see my debug log messages on DebugView utility to ensure everything is working fine and driver is listening to the network traffic. However, if i build same code for Windows 7, it gets build and installed successfully on Windows7 BUT no debug logs are captured by DebugView utility, so that i can assume that the driver is up and listening the network traffic on Windows7 OS. Am i missing something? I tried to build for all kind of architecture but no success to verify the debug logs on DebugView. After reading several blogs i came to know that DBGPRINT kernal level logs are not available in Windows Vista and above by default. I set the registry key to enable dgbprint messages as mentioned here: http://msdn.microsoft.com/en-us/library/windows/hardware/ff551519%28v=vs.85%29.aspx, but could not found any logs on debugView. Everything is working perfectly fine on WindowsXP. Why it is not working on Windows7 ? Please help. -- Regards, Ashish

IMHO this topic would fit better to MSDN forum. M.
