I have an old Windows 2003 Server (DC) running a proprietary old software as well as being used as a file server for a 20 workstation office network.
I'm intending to add a new Windows 2008 server, and use it as backup DC/DNS, and move the File Server role to it as well so that the old server is only running that old proprietary software (since it's taking up a lot of resources).
How would I add the Server 2008 as a backup domain controller to the old 2003 server? I've read that I need to use adprep command on 2003 server, but I'm afraid that it may break something...
Does new Win2008 server need to be added to the Domain before it can become a backup Domain Controller? Currently it's in the Workgroup, I installed ADDS services, and tried to run dcpromo, but it was saying that it couldn't find the DC - even though I entered its IP in DNS and they're connected to the same switch.
Please help. Thanks in advance!
