Have a look at ( even though the error is different the tests on communication and name resolution are valid) http://support.microsoft.com/default.aspx?scid=kb;en-us;q159485 especially try the last test with exchange administrator from the new server. Also make sure that you are logged onto the new server as the exchange service account while your carrying out the installation. Do you get any error messages in the application log when setup fails, if so what are they ?

We are attempting to add an additional Exchange 5.5 to an existing Exchange 5.5 Organization and Site. During install we are able to join the existing site and the information appears to be correct. However during final phase of the install on the new server we always receive an error that directory replication was not successfull. Stop and restart Directory Services and try the install again. Both servers have NT 4.0 SP6a, the existing Exchange 5.5 server has sp4. Please help.........extremely ignorant and frustrated!! Thanks so much in advanced! ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: jamesb@xxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
