High Traffic between My ISA server and the SUS/Symantec Server/Quarantine Server which is one windows 2000 server.it seems that every second a communication is happening. The main files are: qserver.exe (quaratine server), caauthd.exe ( I don't know what is this file), icepack.exe My log files in ISAlog folder are up to 8MB per day (e.iFWSEXTD20040212.log) . I don't know what to do? I have run on the server Mydoom virus removal and other virus removal like stinger.exe from Mcaffee and DoomCln-KB836528-v3-ENU.exe from Microsoft. All results were negative. Please help
