I have active directory with 4 remotes sites and subnets, a remote site connected via VPN has a domain controller. this remote is being bought out by another firm who like to keep the IT equipment. I am planning to demote the server and set new local admin password for the server and workstations, and the on the server
-remove from current domain
- remove DNS server config
- remove VPN
-promote server to domain controller of a new domain with DNS and dhcp
- join all workstations to new domain
as the site has 1 server, it is also running file, print and some applications along with it being part of DFS
anything else I need to consider?
