My business has just acquired a new office and will be taking over their technology and network configs. They have a domain controller which I would like to join to our domain. I've joined brand new DCs to my domain before, but never an existing DC from someone else's domain. Is the process any different? Are there any pitfalls I should watch out for?
My domain already has 2008R2 as the primary DC. The DC being joined from another domain is also 2008R2.
Any insight people can provide would be much appreciated.
