Yesterday I added a second domain controller to my domain. Let's call the old domain controller DC1 and the new one DC2. I'm looking forward to eventually retiring DC1 as it is an old tower style and about 7 years old and doesn't look good in my server cage :)
I also have an exchange server...I mention this because my exchange server get's mad when DC1 is restarted and i have to restart the exchange server every time. It's very annoying to get phone calls at 6 am...
DNS is setup and seems to be working on DC2. It's pointing to only itself for DNS, and the ISP's DNS as a forwarder. DC1 is setup the same, points to itself only, and the ISP's DNS as a forwarder. I have DHCP setup on DC2 (with same settings as DC1, but not activated). DHCP scope options are setup to give out DC1 and DC2 for DNS. I added DC2 as a global catalog server as well.
So onto my questions now..
1) what command tools can i use to verify that things are working properly on DC2? (besides unplugging or shutting down DC1)
2) and what do i need to do in exchange to make sure exchange can see and use both DC's in case one goes down or gets' restarted?
3) Once I acitvate DHCP on DC2, and stop DHCP on DC1....Will DHCP on DC2 know not to give out already assigned addresses by DC1?
Thanks in advance
