System State

Hi Everyone,

I am using Windows 2003 Server Enterprise Version installed on HP ML-150 Server. Active Directory is installed on the server and is a domain controller and global catalog server as well.

I took System State Backup every 3 days. To restore system state backup tell me what I need to do

1. HP-ML150 machine is required or i can restore the backup on different machine with different hardware?

2. Will it restore all the user, group and ou
on the other machine?

Give me some useful links regarding system state backup and restore.
