yep I run ISA server and all the ports are being reported as closed. I would like to stop the server from answering (step 2. below). 42 is the correct answer!

As the 3 way handshake is: Client 1. SYN sent from client ---> Server Client 2. SYN/ACK sent from server <--- Server Client 3. ACK sent from client ---> Server as most scans report a port open when a connection can be made, so to to make ports stealthy they musn't reply to the client computer saying, no sorry port isn't open, which is what they do. Do you run any firewalls there? stu ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: matt@xxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
