I installed the agent (altiris-adlagent-2.6-79.Darwin.pkg) on my 10.6.7 macbook. It showed up in the DS Console (6.9SP4) right away and I was able to push files to it, etc.
However a couple of days after, it no longer shows as active in DS console. I know it is on, but it doesn't appear as on. If I reboot, it does not show up again.
I can ping it, and remote via VNC, but the computer doesn't show as active. Any ideas?
