I
don't see why not. I don't know what the MS digital signature is used for. Does
this indicate a "Microsoft certified" driver? Perhaps there are apps that will
refuse to use drivers that don't have this signature. If you are writing the
application that uses the driver, you don't care about a signature.
Thank you,

Subject: RE: [WinPcap-users] What kind of Windows driver is Winpcap?Hi David,Thanks for the response.I agree that this is a cool feature, and I want to change my NDIS IM driver (which currently needs INF files and must be signed my Microsoft) to behave the same way.Are you suggesting that I could load my driver dynamically from an App if I call the same functions you outlined below? No need to digitally sign my driver with MS?Roger-----Original Message-----

Subject: RE: [WinPcap-users] What kind of Windows driver is Winpcap?The PacketOpenAdapter() function in packet32.c reads the Windows Registry to see if the required entries needed for the driver are there. If they are not found, it calls PacketInstallDriver() which calls CreateService() to create the service on the system. This will place the entries into the Registry. PacketOpenAdapter() then uses various Service Control Manager function calls to start the driver. This all works fine if the driver file is already in the correct directory. If not, the PacketOpenAdapter() call will fail. Most drivers do not do this, but this is a very cool feature of this driver.Thank you,

Subject: [WinPcap-users] What kind of Windows driver is Winpcap?Hi,I have written NDIS Intermediate drivers before for W2K and it required INF files and had to be signed. However, Winpcap does not. Looks like the App dynamically loads it when needed. How is this so?--
