I've downloaded and import the 11.2.3a update in our (lonely) Primary server. No problem for that part.

The problem occurs when I try to deploy this update to the server. I've assigned a deployment to the primary server, the update have the "assigned" status and a refresh on the device must be done to start the installation. BUT, I can't have the server to be refresh. I have no login option on the Adaptive Agent icon, no logout too. The properties page show that it seem not register to the ZCC. Last refresh last from July. I've try 'zac retr' and 'zac unr' and received an "Unable to register any services" error.

Any clue ?
