Install AD for another location with another subnet

Hi Experts,

in one week we open a new location and I need a new AD on site.
Until now no network is on the new site.
Is it possible to install my AD in my site (other network) ?
Can I replicate the new AD to my main DC ?
And my question is, can I change IP address of AD without problems ?

yes but you need to setup a site-site vpn from your main site to the remote site.  it should probably be on its own subnet
arnoldCommented:
Yes.  To dave's point, you can get the DC/DNS/dhcp joined at the main office and place it in a site, then take it to the new location, add the local ip, setup dhcp.
If site to site vpn is not available after Internet access is established, setting up a vpn between the server where DC is running and the main office is an option as well.  Data needs to replicate to the dc to be accessible locally when a site to site vpn is unavailable.

Dhcp option can be used to push routing rules.

Hi,

Are you installing the new Domain Controller in the same domain or are you planning to create a new domain in new site.

If you are adding new Domain Controller to the existing domain, then it will become additional domain controller. It will have to replicate AD Database from existing Domain Controller. This will be done during the installation.

You can install DC in existing site and later move it to the new site. You can change the IP Address of the domain controller. Following article can be referred on how to move a DC to another site.

My subnets are all reachable over my firewall.

10.1.xx
10.2.xx
And the new one is 10.3.xx , but this network is not ready yet.
Therefore I want to setup and replicate the new AD in 10.2.xx and later I want to change the IP to 10.3.xx

Can I change IP of AD ?
David Johnson, CD, MVPOwnerCommented:
yes you can
Eprs_AdminSystem ArchitectAuthor Commented:
Cool, thanks.
Also on the AD I have to install DNS and DHCP.

For DHCP I know I have to setup the range for my clients.
For DNS I have to change the settings on each client.

Anything else ?
arnoldCommented:
DHCP scope options you can push name server records along with IP so you do not need to manually set the DNS.
Make sure your AD configuration is such that local workstations will only query the local site DC and not try to reach any DC in your AD environment............

The site design and placement of this DC in the site where opther workstations will be.

Thanks a lot.

One more thing, can I export my DHCP settings and import to a new location ?
arnoldCommented:
Netsh dhcp server dump
Make sure to change the IP referenced from the server where this is being exported to the IP scope in the new location.  You likely will need a limited portion of the entire config.
Eprs_AdminSystem ArchitectAuthor Commented:
ok thanks.
so you mean I can export the config with this command ?
Netsh dhcp server dump

To import it to my new server with new IP, can I change the IP settings in the exported data ?
arnoldCommented:
Yes, dump is mot import/export type.
It is a text based file of commands.
Netsh
Then paste the adjusted lines/entries from the dump file.
