This section explains how to identify and correct errors that
can occur when you are installing Exchange 2000. Use the following
information to learn more about the problems you may encounter and
how to resolve them.
Cause
This error occurs when the account you use to start Exchange 2000
Setup does not have the permissions necessary to install Exchange
2000 in the existing Exchange 5.5 site. Exchange 2000 Setup
requires service account permissions at the organization, site, and
configuration levels for the Exchange Server 5.5 directory when you
install it in an existing Exchange 5.5 site.
Solution
Ensure that the Windows 2000 account that you are using to start
Exchange 2000 Setup has service account permissions at the
organization, site, and configuration levels in the Exchange Server
5.5 directory.
More Information
To ensure that you have the correct permissions to install
Exchange 2000 Server in an existing Exchange 5.5 site, install the
Microsoft Exchange Server 5.5 Administrator program on the computer
on which you are installing Exchange 2000 Server, and then attempt
to administer servers in the Exchange 5.5 site by using the
Administrator program. If you can start and run the Administrator
program on the computer running Exchange Server 5.5, you should be
able to install Exchange 2000 when you join the server to the
Exchange Server 5.5 site.
Important
Remove the Exchange Server 5.5 Administrator program before running
Exchange 2000 Setup.
