lately i have been playing arround with "net send comp-name message" after upgrading to win2k pro and i coded a nice little GUI to go with net send to make it kinda like an instant messenger service. now i want to expand my knowledge on it once more, how do spammers use netsend over the internet to like advertise porn/colleges and god knows what else has popped up on my screen, i sent my friend my lil app so i could try and talk with him over the internet with it but it didnt work, i made sure he typed "net start messenger" to ensure it was turned on but still no success...

he uses windows XP pro, is it a conflict between the operating systems? or is there a special way to use netsend over the internet... i have asked this question on another forum and they just gave me childish responses saying that im just going to create another annoying spamware app, i assume they responded like that because they didnt know the answer, but who knows. any help on this issue would be greatly appreciated....

oh one more thing, is there a way i could have my application detect if net send is running or stopped? that way if its stopped i could have it alert them to turn it on if they want to use the app, i wouldnt forcefully turn it on because thats just rude and they probably have it off for a reaosn, I.E. no spam lol.

once again, thanks in advance for any help.
