Howto add a group to local security policy item?

[time.table]

Hi!

For converting a windows 2oo3 server into a workstation I followed the Windows 2oo3 Workstation instructions. And I use nLite to have Windows 2oo3 workstation CD image and I need help for a last thing.

Almost all setting are stored in the registry and I get the key by using the reg shot utility. But adding a group to the local policy list is different. Reg shot doesn't find anything changed. Maybe is it because it is a list of SID and not "only" a flag: I want to add the group "Users" to the list of group allowed to shutdown the system...

Does anyone have experience in adding a group to a local policy list item?

Any help is appreciated!
