Just making sure I'm not the only one seeing this...
When setting up a static query ("Advanced Computer Search"), I have the criteria for "Managed". This lets me select managed, or unmanaged.
When setting up a smart group, I only have "Managed by:"... with the options for blank or our management account. End result is likely the same, but seems like a bug to me... I'm simply trying to set up queries that omit unmanaged machines.
