Since we have a new exchange server installed in our organisation (see history here : http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/ac89a78c-0a54-4940-9719-74f4cb1cfdf3/#ac89a78c-0a54-4940-9719-74f4cb1cfdf3 )
We have encountered some problems regarding rights and such, so I checked the AD groups and to my suprise I see this :
My question is : How can restore everything to default , I read a couple of threads, but I couldn't find the answer , I already tried a setup.com /PrepareAD but that didn't change anything.
We decided to have one Exchange Server in our organisation for now, but we had 2 in the past until things went bad after a Rollup update.
What's the best way to get everything the way it was a fresh install without completely reinstalling everything (we can't because this is a production server).
Many thanks in advance!
