Clients not communicating with ePO 4 server

I have recently upgraded to ePO 4.

All seemed to working fine until I notice that my clients are not communicating correctly with the server.

when i do an Manual update I see that the clients are getting the updates from ePO_{epo server} rather than connecting to ePO4_{ePO Server}

Clients are suprisingly getting correct dats and have upgraded to the latest AV Patches and Agent version. But ePO does not recognise this.

I have had a look through the SQL and my clients have seemed to stop communicating on the 21st of April (When I upgraded)

Any thoughts?

RE: Clients not communicating with ePO 4 server

I have a fresh install of ePo 4 (not an upgrade), and when I manually update my clients they connect to ePO_{server}.

I'm not sure why you are seeing ePO4_{server} in some of your logs.

I'm running the McAfee Agent 4.0 (not sure what version of the Agent you are running)

RE: Clients not communicating with ePO 4 server

We had the same issue. We had to uninstall the agent first.
FrmInst.exe /forceuninstall
Than reinstall the agent.

You can see the McAfee Agent Activity Log:

I will give this a go.

Got a few test PCs to see if this will give me some results.

Did you script the uninstall and reinstall of the new agent. Can you post what you did

RE: Clients not communicating with ePO 4 server

is it possible that your Epo Security Keys after the Upgrade have changed?
i mean the Agent-server secure communication keys under Configurtaion-> Server Settings -> Security Keys.

When there is one Key which is showing not the correct numbers of clients u messed up something there.

RE: Clients not communicating with ePO 4 server

This is what I got where you have suggested.

I have no idea if this is correct or not

Agent-server secure {Server Name} (jHmj3CGX80KM5eoW37PF4yogsp8=) - 0 agents
communication keys: Legacy (HMW9L9yM2AbJY8qrvmNCNJpYXAI=) - 3074 agents - Master

Local master repository key pair: {Server Name} (uOAAxMx7ra9932HmE9WxiW4VwbE=)

Other repository public keys: McAfee (H7LGlPbFtbARjG6MsNaop1QOFaU=)

RE: Clients not communicating with ePO 4 server

This should be ok.
On the System Detail Page from an system shows there "Last Update" a valid date or does it shows the Date before u upgraded to epo?

When it shows the correct Date, why again u think then its not correct reporting?

RE: Clients not communicating with ePO 4 server

So its not reporting the new Dat, new Agent, nor that its running Hotfix 8

RE: Clients not communicating with ePO 4 server

in System details click on Show Agent Log.
Are there any failures?

When not click in the top of the agent log on View debug logs: FrameSvc current
Search for failures there.
