VMM 2.0 Server now not licensed

[Rob Buxton]

I have VMM 2.0 installed and a couple of VMWare ESX Servers.
One has a full license, the second is new and I've used a temp key while the full license gets sent.
I licensed the Server okay and all was working okay.
But I was having a problem with the HP Insight Agent. So I removed and reinstalled it, along with SNMP.
Since then the VMM claims this Server is unlicensed. I had a similar issue with VMM 2.0 and I traced that back to SNMP Settings being awry. But, these are correct. I'm using the Global Settings and I can snmpwalk snmp from the HPSIM Server using the community names.

So, what else does VMM Licensing rely on?
I've tried re-adding the license key, but it just states the Server is already licensed.

I've rerun Identification and Data Collection tasks.
