Thanks Shivi !!! Tom, I ran this on the DNS server with the All PROTOCOL rule on and then ran it with it off. This is isn't a very busy server, so it isn't like I am missing it, but there appears to be only one connection change which is TCP 3389 taking place if the DNS query is successful???? I will also add that there are two public DNS servers sitting behind the ISA and both have same problem without the ALL PROTOCOLS rule open for them. One DNS server is on 2k and one on 2k3...just more info. Sorry, I am not very sharp on sniffing. -John
