Issue modifying local security policy with secedit

I'm having an issue modifying local security policy on my machine using SECEDIT

When I run:

secedit /export /cfg c:\temp.cfg /areas SECURITYPOLICY

I get a copy of the configuration just fine.

However, when I modify this file and try to apply this new configuration with:

secedit /configure /db c:\windows\security\local.sdb /cfg c:\temp.cfg /areas SECURITYPOLICY

I get the following message:

Completed 5 percent (0/18)    Process Security Policy area
Completed 22 percent (3/18)   Process Security Policy area
Completed 44 percent (7/18)   Process Security Policy area
Completed 61 percent (10/18)  Process Security Policy area
Completed 77 percent (13/18)  Process Security Policy area
Completed 100 percent (18/18) Process Security Policy area

The task has completed successfully.
See log %windir%\security\logs\scesrv.log for detail info.

However, none of the changes take place when I re-export the security policy file.

Thanks!
