Hi Folks,

I am trying to install the E2k10 Sp1 on Exchange CAS server in a Child domain but I am receiving error in the organization prerequisites  checks "Error: Setup need to contact the Active Directory site as Schema Master..... This computer is not in the same Active Directory....."

This Exchange is in a Child domain and the Schema Master is located in the root server but the child domain are able to contact the schema Master ( Ping and netview is working). We have opened a ticket with MS but still it is not fixed. Any Help will be appreciated.

Thank,
Libet

You haven't posted the entire error message, but the problem will come down to the fact two of the schema update commands (setup /ps and setup /p) MUST be run from a server in the same domain and site as the Schema Master - i.e. the forest root domain.

This means you will need logon access to the forest root domain, preferably with Enterprise and Schema Admin rights in order to make the changes.

Logged in to an appropriate server in the schema master's domain with the above permissions, open a command line and run setup /ps from the Exchange downloaded SP1 media. Then run setup /p.

Once you have done this, allow sufficient time for the changes to replicate across the forest.

You then need to run setup /pd in at least the domain where Exchange resides, and possibly others depending on your infrastructure.

See http://technet.microsoft.com/en-us/library/bb125224.aspx for more info on the commands and where they can be run from.

Hi tigermatt,

Thanks for your reply yes we were able to install it after I run manually the schema update at the root server.
