We are planning to migrate our current domain controller to a new machine with better hardware. Our current domain controller is creatively named "domain". The new DC will be named "Master".
My question is all our machines and webservices login/authenticate through domain.company.com, if we migrate to the new machine, master.company.com, will those clients that log in be able to because of the name change? Or would I make a new A Record pointing 'domain' to 'master'?
