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 secpol.msc).

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.
