There is only one DC, and it's older, and I don't want to take the chance of causing issues by changing anything on the 2003 SP2 DC. This is only a bandaid until I can add more servers and have more time to make backups, etc. I've just been hired in and found the network woefully lacking, and just want a bit of failover redundancy.
So, will the 2008 R2 DC work as a failover DC in this 2003 DC functional level without adprepping?
Thanks.
