Error Polling Agent

by Jul 11, 2013

Two of our VMs were moved outside of up.time’s scope within vCenter (they’ve since been put back) but this appears to have had an effect on the communication between the monitoring station and the agents. The error when Polling the Agent is below:

I’ve uninstalled and re-installed the Agent on both clients but with no success.

 

Thanks,
