When connected to DeviceLock Service on a remote client with DeviceLock Management Console, an attempt to open Audit Log Viewer gives 'Access is denied' or "The requested operation is not supported" error.


  1. The errors may indicate that the currently connected user does not have enough privileges to view system event logs.
  2. There is a known issue with Microsoft Security Updates released on June 8 2021 (or later) for Windows 8.1 & Windows Server 2012 R2 and Windows 10 & Windows Server 2016. Whenever it is not yet installed on a local (server) or a remote (client) machine, applications that are using certain legacy Event Logging APIs might fail to display event logs information with different errors, for example:
  • Error 5: access is denied

  • Error 1764: The requested operation is not supported.

  • System.InvalidOperationException,Microsoft.PowerShell.Commands.GetEventLogCommand

  • Windows has not provided an error code.


  1. Make sure that the account used for remote connection is the member of "Event Log Readers" group on the remote machine.
  2. Install June 8, 2021 or later Security Updates BOTH on the computer(s) with DeviceLock consoles (server) from which you are connecting AND on the remote clients.
