From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "UserVars.DcuiTimeOut" value and verify it is set to "600" or less and not "0". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name UserVars.DcuiTimeOut If the "UserVars.DcuiTimeOut" setting is set to a value greater than "600" or "0", this is a finding.
