Polling interval (sec): 600

Update time (hh:mm): from 00:00 to 23:59

OK, so the polling interval of the host(s) match what the group has, the update is scheduled for the group and the MC still doesn't show an scheduled or available\needed update for those particular hosts.

There are a few reasons this might be so:

#1 the hosts is running an unsupported OS platform (XP SP3).

#2 is sometimes hosts won't accept an update schedule if they are in test mode AND the original group the agent kit put them in to is gone.

#3 is a CSA version mismatch, the version on the host doesn't exist on the server (but I think you ruled that out).

Not much else I can suggest without actually sitting in front of it.

The hosts are running XP SP1, in enforce mode and there is not a version mismatch. So I guess these machines will have to be upgraded manually.
