Hi,
I have a single domain in 2 sites with 2 DCs each: DC1 and DC2 in Site1 and DC3 and DC4 in Site2. Both sites are in different subnets.
I am required to change the subnet in Site1 which means changing the IP addresses of DC1 and DC2.
- DC1 is a DHCP and DNS server
- DC2 is a DNS server
- DC1 uses DC2 as its primary DNS server, and itself as the secondary
- DC2 uses DC1 as its primary DNS server, and itself as the secondary
I'm wondering what the right order to do things is.
Does this seem right?:
1. Change IP + Gateway + DNS servers of DC1
2. Run "ipconfig /flushdns", "ipconfig /registerdns", and "dcdiag /fix"
3. Repeat Steps 1-2 for DC2
Is this all I need to do? I don't need to touch any of the static DNS records of the DCs right? Will replication from DC 3/4 in Site2 work properly?
I already know I have to create a new DHCP scope, I created a new reverse zone in the DNS, and I added the new subnet in Sites and Services.
Thanks
