AD Connect - Re-install Question
AD Connect - Re-install Question
Hi All,
Just wondering if anyone has any experience with re-installing AD Connect. It was installed quite a while ago and some of the options that are there in the install now as far as I am aware were not available when it was first installed.
This option we need '(User Identities Exist Across Multiple Directories) - ObjectSID and msExchMasterAccountSID ' is not able to be changed retrospectively from what I can tell.
Therefore I believe a reinstall is our only option get this option selected.
I'm just wondering if I can simply install this over the top of the existing install?
I noticed there is a SQL database and I have read about the option to 'use existing database - install mode' however this looks like it defaults to express mode which is no good for us as I need to select these advanced features.
Any help would be greatly appreciated.

You should uninstall before you reinstall. The SQL database is used to speed and handle syncing, but the actual properties to match accounts are stored in AD and AAD, so you'll have to do a fresh full sync (which is slow comparatively) but you won't usually break anything with a clean install. You'll want to clean up the old service accounts though, as new ones will be created by default.

Thanks Cliff,
I see one service account called NT SERVICE\ADC (something) is that to be removed then?
Will an uninstall remove any sync’d accounts from the tenant?
Can I use the same database or will that be removed with the uninstall?
Thanks for your help
