Are you using a domain account from your child domain that has been added into the Enterprise Admin group? If not you won't be able to install. To add an account you also have to have both domains as Native only and not mixed mode. Been finding out all this fun stuff over the past weeks. Slowly losing my cool with AD!!! Good luck Piers -----Original Message----- From: Qusai Ali AL Haddad [mailto:qusai@xxxxxxxxxxxxxx] Sent: 23 August 2002 11:20 To: [ExchangeList] Subject: [exchangelist] exchange server 2000 in child domain http://www.MSExchange.org/ dear sir , i cannot install exchange server 2000 in child domain ... regards Qusai ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: pwhite@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
