creating a new domain on the same IP range as a pre existing domain
Posted on 2009-02-12
The company I've just joined are all on a workgroup using the DHCP of an already existing domain (dif company but the bosses of both are related... )
They need their own domain, quickly so I know this is the "quick and dirty" way of doing it but as we dont have our own internet connection I was looking to do a DCPROMO on the 2008 server we have set up as a file share, create it as a DC on a new domain, setting up DNS and leaving the DHCP same as is. Then setting up my users in AD and migrating them off the work group and onto my domain.
My concerns are whether or not there will there be a problem with mulitple domains using the same DHCP and that in my ignorance i'm missing something/not doing something I should and if it all goes wrong... will I be able to demote the file server back to its original state and wait for the purchase of our own line/router/firewall
Could someone point out the holes in my plan please
