Hi.
It is true, the so called "generic ndiswan adapter" is always listed on XP (provided that you have the rights to access the netmon driver). Even if there is no dialup or similar adapter installed.
However, choosing such adapter should not cause any crash in any case (basically, if you don't have any ppp hw, you won't capture anything). WinPcap forwards the request to open such adapter to Microsoft netmon (that's what we use to capture from PPP), and the request should either fail (we deal with such errors in winpcap), or succeed (and then you don't capture anything). I had a look at the winpcap code for that, and every return value from the NetMon API seems to be checked.
Can you tell me the exact error message you are encountering? In the next weeks I will try to replicate it on one of my machines.
Have a nice day GV

Hi,
I noticed that on some installations there is always an entry returned for the generic driver even if there's no such hardware available.
If a mainboad contains a miniport slot for either a miniport dialup modem or a miniport networkcard, at least Windows XP will install a miniport driver (recognized by the library as a valid entry), but because the actual modemdriver or networkdrivers are not installed, trying to access it will crash the software. Anybody has similar experiences? or better a solution to distinguish between an actual filled and properly installed slot and an empty slot/ rogue miniport driver? I am talking about otherwise clean machines who never had the miniport slot used.
Regards,
Thaddy
