Question : Backup AD, DHCP & DNS

I have a 2003 server that has AD & DHCP & DNS installed and I would like to schedule a daily backup for the databases and system state.

I prefer if I could do this using a batch file using task schedule or any easy method that do not require me to purchase 3rd party.

help is highly appreciated

Answer : Backup AD, DHCP & DNS

Here is what we use on our DCs.. edit the backup destination, save as a bat or cmd file and run as a scheduled task.

@echo on

c:\windows\system32\ntbackup.exe backup systemstate /j "System Backups" /f "d:\backups\%1.bkf
