Refreshing group policy - 2000/XP/2003

I keep forgetting how to refresh Group Policy on a Windows 2000 client:
secedit /refreshpolicy {machine_policy | user_policy}[/enforce]

The command changed from secedit to gpupdate in Windows XP and Windows 2003. From the secedit help file:
secedit /refreshpolicy has been replaced with gpupdate.

GPUpdate [/Target:{Computer | User}] [/Force]
