Hi there!
I'd need urgent help with an network problem from you real code-gurus!
I'm getting mad. I need to capture an network stream that i can see with ethereal (plz look at attached picture), but even googling for more than an week now, without luck or even any idea.
The stream comes on netbios-ssn 802.3->LLC. HOW CAN I ACCES THIS STREAM FROM VB6??
Plz help, need a couple of sleep...or coffee.... #*+@=/..
