On XP 8.7i machines connected to my EPO 4.5 server (Agent 4.5 P1), the On-Access Scan Messages window doesn't pop up when a virus is detected. The same machine connected to my old 3.6x server does display the message.
I've ensured that "Show the messages dialog box when a threat is detected and display the specified text in the message." is enabled, and has a custom message. This also displays as enabled on the client.
If I go into Tools, On-Access Scan Messages, then the Viruses are listed, with my custom message. I have tried modifying the message to see if it was the cause with no success.
So what am I missing?
