Q6850003: When I try to setup a new Event Log check in the Manager for one of our old Windows 2003 servers, I get an error saying: "Unable to retrieve a list of Event Logs from the remote computer. The machine is either not accessible, or the remote computer does not run Windows 2008 or Windows 7 or higher.".
If you have Network Monitor running on Windows 7 workstation or higher, or Windows 2008 workstation or higher, you can monitor any Windows event log, not only the standard Application/System/Security logs, but also the extended .evtx logs. You can query any windows computers except Windows XP, Windows 2000 and Windows 2003.
