I have inherited a VMWare environement ESX v3i 3.5. I am not fluent with VMWare ESXi so bare with me. Two days ago, when I opened Virtual Centre, one of the Hosts showed up as Not Responding.

The error I am seeing is:-----

Unable to acquire licenses because license source is unavailable: The license manager has not been started yet, the wrong port@host or license file is being used, or the port or hostname in the license file has been changed.

What I have tried:

• I have Stopped and Started the license server within the application. When I do this, I am able to disconnect the host in Virtual Centre and reconnect. This brings the host back online, but a few minutes later, the host goes to a not responding state again.
• I have rebooted the server with the Licensing software installed.

While browsing Google, I have not been able to find any steps I feel comfortable performing and I would like the opinion of the VMWare pros.

Where are the log files I should be looking at to correctly determine what is going on? Has anyone seen this behaviour and how did you resolve it?

Thank you
