esx server not picking up its license

[mcollins101]

I had to rebuild one of my esx servers yesterday - but it now won't pick up it's license from the license server. Is there anything I should be doing to ensure it can?

1. Was it an upgrade or a complete reinstall?

2. If it was a full reinstall, did you remove it from vCenter BEFORE re-adding it?

It was a format and install from clean

No I didn't remove it. I just reconnectedd to the ip address of the server after it came back up

disconnect and remove the host from vCenter, then "add host" back in.

Okay

Have a look under ADMIN>Licenses. I am guessing you have no licenses available (because it didn't drop the license from the previous install)

You will need to remove that server from vCenter and then refresh your license server (using the FlexIM license software that vcenter installed to your server)

Once you can see under ADMIN>Licenses an available license, readd your server and you are away!.
