back to the subject
about sharing the files acroos IMESH or KAZAA i faced a prob which is when i share the file and serch for it i dont find it online

i think the cause is that i was using a shared internet cnnection on lan
so i think the 1 who has the real connection was doing something for security and that made the computer wont share i think

any way the need for this was solved latley
thanks again
