Hi, I have Norton Antivirus 7.6 corporate edition on all my workstations, my workstations are all Windows XP Professional. After rolling out XP SP2 on some test workstations I have found that I cannot connect to the clients through the symantec system centre. If I restart the Norton Antivirus service on the affected workstation I can connect, check logs, run scans etc. If I try to connect again a short time later then the same problem occurs. Has anyone have any ideas?
