Situation

This article discusses how to resolve discovery failure with error "Value cannot be null. Parameter name: version ".

When attempting to discover a Windows 2003/Windows 2008/Vista machine, following error appears in the diagnostics:

       <message>Value cannot be null. Parameter name: version</message>

If a WMI query is run against the machine being discovered, "access is denied" error is received.

Running MSInfo32 returns error "Can’t collect information Cannot access the Windows Management Instrumentation software. Windows Management files may be moved or missing" .

Resolution

The "SERVICE" account must be added to the Administrators group. This will give permissions to the system to access the WMI classes as well as allowing MSINFO32 to access them.
