I am new to ISA and have it running on SBS 2000 .I am also running
Exchange. I am concerned the system has been compromised. On my ISA
reports I am getting a high percentage of  unknown protocol useage.
How can  I determine what the unknown protocol is ? Do I need to 
configure more packet filtering ?
