Hi:

I use the devcon.exe to install/remove an NDIS driver. On Windows XP
machine, I can install the driver multiple times with no problem, but I
could not remove any of them; when execute "devcon remove mydriver", got
error message "no device removed". But it works fine on a Windows 2000
machine.

Any information is appriciated ! Thanks In Advance !

Does the NDIS driver have the NCF_NOT_USER_REMOVABLE bit (0x20) set in
its registry "Characteristics" entry? See also
