[Aside] AD Sites, Subnets, Trusts, etc.

  • How Domain Controllers are Located Across Trusts – this is a delightful article. I don’t know why, but I simply loved the way the author presented the information. Very logically written. Wish I could write blog posts with such clarity.
    • Praise aside, it is a good article on how subnet and site definitions are used to find a Domain Controller closest to you, and especially how it works across forest trusts.
    • Update: There’s a part two which I came across later. This covers a specific edge case.
  • Using Catch-All subnets in AD – Wanted to know how catch-all subnets in AD Sites will interact with specific ones. This one explained it. The specific one takes precedence. Which is exactly what you want. :)
  • Do cross forest trusts need PDCs that can communicate with each other? The answer seems to be NO, check out this discussion for more.
