I’m still having problems unloading the NDIS driver. The machine seems to go into some sort of a “busy wait” when unloading. Can someone enumerate as to what the potential problems might be, and how I can detect and resolve those?. Are there any other tools / windbg commands that I can use to debug this problem?
I guess first I need a clarification on why there are so many handlers for unloading the driver/ or its bindings AND more importantly what is the order in which these are called? (ok driverunload is probably the last, but I still want to be sure)
There’s driverunload, MPHalt and UnbindAdapter handler
Regding DV I had the following q. :
Bad clean up of objects (DV should detect that, but the part I didnt understand was the issue as to which checkbox I have to enable to ensure that unload checking is *definitely* done. In my case I have all 4 checkboxes except “Low resources simulation” checked)
Thanks

Yep. DV didnt throw up any exceptions, whcih is why I dont have a straight clue that I can jump on. Please let me know if you guys come up with other ideas…
Thanks
