Thanks Matt, Mark and Merril (ok thats strange... 3 ppl responded all started with the letter M - what is the odds on this happening ?-) But luckly the server is a complete AD server on it own (want to lean about that aswell :-) with just about everyting installed- dns, iis, sql and what have you..... Didn't wanna mess up the corporate net in anyway - if i could avoid it.... all we have now is a trust between my test domain and the real domain..... so it should be preaty simple to clean up - just remove the trust and take my server down..... -----Original Message----- From: Walkowiak, Matt Sent: Wed 8/7/2002 3:41 PM To: [ExchangeList] Cc: Subject: [exchangelist] RE: howto: move storage groups http://www.MSExchange.org/ Stig- Since you installed a "test" install of Exchange, I imagine you will at some point want to uninstall it. It is OK to uninstall it, but don't just shut the Exchange server off when you're done with it. When you install Exchange, it modifies Active Directory. If you just turn the Exchange server off, those modifications stay around, and we all know what stale data can do to a network. If you do a Remove of Exchange, that should take care of the Active Directory items. Matt Walkowiak
