After upgrading to 10.3.3 and encountering other issues, when trying to uninstall the agent from a machine we get an error message that the zone connection information is incorrect when using the default settings. However, replacing the FQDN of the server with the IP address lets the agent uninstall successfully. Even after reinstalling, the same error occurs again. I have no problem pinging the server name so it doesn't look like a DNS issue. Has anyone seen this behavior or have a suggestion of where to look to troubleshoot?
