I just ran into this today. The problem was an un-checked setting in the console.
When connected and logged in to the console, select the Tools menu, then Symantec System Center Console Options. At the bottom of the first tab (Virus Alert Filter), check the box to display the infected state of each client.
Because I have the console loaded directly on my desktop (as opposed to running it on the server), I had to save the settings for them to stick AND the SSCC had to be run as an administrator or it wouldn't save any of the settings at all.
Now I'm dealing with a situation where I can't take action on items (like deleting an infected file) because it won't let me do it from the console on my desktop, even when running as an admin. I can still perform the functions on the server, but that defeats the purpose of having it installed on my desktop.
Hope this helps you.
