Currently on AD using Windows 2012 r2 Domain Controllers. We want to do a DR test to see if users can log in if our main headwaters DC is down by being authenticated using a remote location DC. I want to to test it on one pc and force the pc to use the secondary DC while the Headwaters DC is still up.
I have tried editing the host file using #PRE and #DOM etc, no luck, removed the headquarters DC DNS entry using only the remote DC DNS with no luck.
Client machines are Windows 7.
