Some of you may have gotten a pop-up windows box before with a message about airlines, diplomas, etc. I'm pretty sure these spam advertisements are sent with the net send command :
net send <ip> <message>
We've used this in school, at lan parties, etc. My question is how do i disable this command for anyone not on my workgroup? I don't want to use a firewall if i can avoid it. Also, how can i password protect/restrict port 139 access to anyone now in my workgroup?
