Moved to our ePolicy Orchestrator area for better attention by an expert.
Could you please provide a little more information on the nature of the problem ?
Are there errors in the agent log for example ?
What is different about these machines compared to the working ones.
- Do they run firewalls?
- Are they at the end of a VPN connection?
- Are the on a different subnet?
- Are they cloned installs?
Flesh out the details and it will make diagnosis easier.
I'm having this exact problem also, not sure when it started.
I first noticed it when I pushed the agent to a new server on a new subnet so I thought it was FW related. I then check some existing clients and some are having issues also. In particular I have 2 machines on the same subnet that haven't been modified in forever... one works one does not.
Right click "Update Security" works
The following do not:
Collect and Send Props
Check New Policies
The all give "Agent Failed to communicate with ePO server"
Is there a licensing cap that is enforced I'm wondering? I don't know what else to check seeing as how the machines are on the same subnet, same version of agent... New server is still experiencing issues but I'll solve my local problems first.
Many many things can prevent an agent from communicating. Post a copy of the agent log from a client machine failing to communicate and you will probably get some more helpful responses.
