Re: [ActiveDir] [OT] Uninstalling Exchange - how does this modify AD, what alters in AD
No, you are correct in your assumptions. There are changes on the local server, yes. Many many changes. But you also must make changes in the directory from name res to the directory itself. Exchange relies on Active Directory for it's directory services. It has none (well.. mostly not one of it's own) of it's own and therefore stores all kinds of information in the Active Directory. It then shares that information by populating that information and replicating to the far reaches of the directory footprint. User objects also have information about servers stamped on them. One of the removal steps checks for that and warns you etc. Other servers will look there to initiate routing topology building. There are smatterings of Exchange information in the directory that have to be removed in order for the removal to be complete. What you *could* do, if you want a complete list is to install some, then run through the removal with a network trace and or increased logging enabled to watch the whole thing as it goes through it's work. I'm not sure the removal process is well documented anywhere else to that level. If it is, I haven't seen it and trusted what I saw to be up the minute accurate.

I agree with that. Besides that, my description of the situation is probably not as clear as it should be.
