I am using CSA 22.214.171.1249 and am seeing hosts (desktops and servers) that detach themselves from all groups. Even though they were installed and registered with the MC months ago, they say they have a recent registration time. All of the agent kits for these hosts are still listed in the MC. They also show the following event:
"No security policies are being enforced on this agent. This could be due to an incompatible software version (the agent is running version 126.96.36.1999) or the agent has re-registered and the original installation kit has been removed. This agent should be added into the correct group(s) and the rules regenerated as soon as possible. If the agent software is not current, then it should be updated."
Does anyone have any ideas?
I've seen where an agent kit is reinstalled and it has no group associated with it.
I've also seen this from machines that were deleted from the MC and the original group it attached to is no longer there.
Do you have a forced install for your PCs?
We push a silent install via our software deployment application, if that's what you're asking. Sometimes this occurs and there are multiple hosts listed in the MC with the machine name in question and sometimes there is only a single instance of the host in the MC.
However, we have not deleted any groups.
A silent install should not install again on a host unless it is a newer version. Are you saying that this occurs and you get duplicate hosts?
If so, that may be related to your problem. Some hosts may register again and others may just get knocked off (yeah, that's a technical term..).
Is this a standard software deployment app like SMS or ZenWorks?
We use Zenworks but it doesn't try to install unless there is no okclient.exe present. Even if it does, it says "client is already up to date" or something like that.
We use a standard software deployment app. The app keeps track of which apps it has pushed by marking a flag for that package. So will not get installed again unless the flag was manually removed, even if we updated the agent kit install executable.
I believe we see duplicate hosts because the machines were reimaged (with the same hostname) and then CSA was installed.
if you see duplicate hosts in host list I`ll recommend that you delete both entries and let the agents (re)register themselves. This could happen under particular circumstances.
Brian, did the agent kits that installed these hosts belong to any groups? If not, try creating another kit that belongs to the group(s) you want these hosts to be in and install it on a couple of problem hosts.
Does it happen often or infrequently? I am running in to a situation where some hosts will revert to the original group they belonged to with a new registration date and I haven't deleted them.
Tom, the agent kits used to install these hosts were attached to a number of groups. It seems to happen once every week or two. We'll just notice a few machines sitting in the MC not associated with any groups. We have since setup an e-mail alert about this, but we'd still like to find the root cause and fix it.
So more information has come to light. The machines that are experiencing this issue have all are being installed with agent kits that are no longer in the MC. We have searched the audit trail but there is no record of them ever being deleted.
Has anyone else noticed agent kits disappearring from the MC in v188.8.131.529?
No, but if the groups that the kits were associaed with were deleted this could occur. See if any groups were deleted (and recreated with the same name maybe?).
