My company is migrating/consolidating domains with several remote business we have purchased, and one of our remotes sites has a pre-existing IT department that we want to keep in place. We would like to give the pre-existing department access to manage their users, groups, and PCs with out giving them access to anything else in our network. Has anyone dealt with this before, and if so how did you set this up?
Edit: I want to specify that this new company will be on the same domain as our existing company. So I need to figure out how to make this work all within one domain.
