We are trying to setup a New Exchange 2010 servers in our office.
Already SiteA exist with Exchange 2007 machines running, now we created different site (SiteB) and trying to install Exchange 2010 servers with DAG.
We are getting below error while installing the pre-requistes for Exchange 2010.
"Setup needs to contact the Active Driectory schema master but this computer is not in the same Active Directory site as the schema master (SiteA)
Setup encountered a problem whle validating the state of Active Directory. Exchange organization-level objects have not been created, and setup cannot create them becasue teh lcoal computer is not in the same domain and site as the schema master. Run setup with the /preapreAD parameter on a computer in the domain ABC and site SiteA, and wait for replication to complete."
Kindly advice......
Never giveup till you get what to want.
