After assigning the 10.3.2 upgrade to my server, sat servers and 1 workstation. All of them are saying "Invalid Registration Key" when I click the Register button in the properties of the agent. The log file in debug mode reports nothing when clicking the Register button. I have not deployed the update to my 500 workstation, fearing I will have to clear my ZIS Info or unreg and reg all my workstations. Does anyone have a clue what could be happening?

Some of the workstation show this in the ZCC instead of the "Green Dot"
"The agent service is running, but the request failed for one or more known addresses."
