I have two identical machines running Windows 7, and I'm trying to replicate the security policy settings of one on the other (these are the settings under
One machine has a setting
Local Policies > Security Options > Network security: LAN Manager authentication level setting of
Not Defined. The other has one of the options selected.
How do I reset that option to "Not Defined"? It doesn't appear in the list of options when I open its properties and there's no visible action to clear it.
