Setting W2k3 BDC
Posted on 2009-04-29
I have an existing windows 2003 domain controller, with active directory, dhcp, dns and file server set up on the same box. lets call this 184.108.40.206
But for safety (after very terrible experience) I wanted to set up a Backup Domain Controller (BDC). The process seems easy enough. I setup W2k3, add role as AD and then set the new box as NOT the first DC on the domain. After following through the process I end up with a server that has AD installed, which seems to mimic the PDC. So it seems to serve its purpose.
The problem is that only AD is created on the BDC. It did not create the DHCP and DNS and File Server part.
So the questions are:
1. IF the PDC fails (knock on wood), how would having just a backup AD help, without DHCP and especially without DNS part?
2. It would also help if I get to keep the File Sharing (Security & Privileges) settings.
3. Are there additional steps I need to do on the BDC, in case the PDC fail?
4. How is this better than setting up a backup hard disk so that I can simply replace the damaged PDC? (Although my backups have never succesfully restored a system, I always end up re-installing from scratch manually.... so a hint on this part would also be appreciated).
