ePO 5.1 failed to activate agents

Hello,

in our business we have problems with some workstations (more than 20) by the moment. Just an example.

This workstation has the agent 4.8 deployed (last version). Also last version of Mcafee antivirus 8.8.

It is reachable from ePO and is also enabled acces by c$ and admin$.

Ping response and there is no Firewall between ePO Server and workstation.

I have uninstalled manually the agent and i have installed again.

Also the admin that we are using from ePO is an admin too in the workstation.

The workstation is not duplicated.

Still not working

We get this error:

3/03/14 17:42:54Waking up agent W1001259 using NetBIOS
3/03/14 17:42:54Unexpected HTTP response code 500 received from remote computer
3/03/14 17:42:54Wakeup agent failed
3/03/14 17:43:52Expired. The task will be stopped.

Can someone help me? Is a really weird bc i can't understand why i can't activate the agent, if I throw de deploy of the agent it works but when I try to activate it then I et the error that i showed before.

Thanks a lot.

Re: ePO 5.1 failed to activate agents

Please check the below :

  1. Firwall locally
  2. DNS record can you ping the machine by name and IP ?

Re: ePO 5.1 failed to activate agents

Hello, thansk for answering.

There is no a Local Firewall between computer and ePO Server. Also Windows Firewall is disabled.

Ping is working fine by name and by IP even doing ipconfig /flushdns (just in case).

Still not managed...

Re: ePO 5.1 failed to activate agents

hi,

did you upgrade your ePO from a previous version? I think there was/is an issue when upgrading from ePO 4.x (5.0?) and MA 4.8 to ePO 5.1 that clients may unable to connect to ePO. As far as I know there is a hotfix available.

Moved to ePO for better handling.

Re: ePO 5.1 failed to activate agents

Hello,

yes. We did an upgrado to 5.1 version from 4.5 i think. Firstly going through the 4.8 version.

So if there is a hotfix to fix this problem you know which one is it? Do you have a link or the name of the hotfix?

Thank you.

See KB79715.

Re: ePO 5.1 failed to activate agents

Hello,

it says that is not allowed to install this hotfix because is already installed (epo 5.1.0.522).

I don't know what else can I do...

Re: ePO 5.1 failed to activate agents

Hi Miguel, did you try what I told you about deleting the embedded credentials agent with the /forceuninstall and trying to install the standard McAfee Agent.

You should check the agent log and see what happens when trying to connect to ePO server
