After the upgrade to 9.5 on the Core and our Agents, I have been occasionally (and without any obvious correlation) seeing this error when trying to deploy packages. It will Multicast and Discover, but when the package would execute it goes to this error message before it actually begins. Reinstalling the agent has not changed anything. Depsite what the error message says, a user HAS logged into the computer, and in addition, the package is set to install whether or not a user is logged in.
Does anyone have any idea what this error message is trying to tell me? If any more information is needed please let me know. Thanks in advance!
