SYMPTOMS

In a mixed Exchange 5.5 and Exchange 2003 environment, you install a new Exchange Server 2003 server. The Exchange 5.5 service account specified is an account in a two way trusted NT domain. The account logged in during the installation process is a Domain Admin and Exchange Full Administrator from the Active Directory domain. The Active Directory account and the NT account have the same account name (and in this case, the same password).

Setup fails during the "creating system attendant object" phase. The following error is seen:

setup failed while installing sub-component System Attendant service with error code 0xC0070005 (please consult the installation logs for a detailed description). You may cancel the installation process or try the failed step again.

The following error occurs in the ExchangeServerSetupProgress.log file on the Drive C:

[00:00:35] Creating system attendant object
[00:00:35] Entering

           Error code 0XC0070005 (5): Access is denied.

CAUSE

This problem is caused because the Active Directory account that was used to install Exchange (account used to log onto the new Exchange 2003 server) has the same account name as the Windows NT account selected as the Exchange 5.5 admin account during the installation process.

Note During the installation process, the 5.5 service account is automatically selected and is not editable during setup.

RESOLUTION

You can select a different account to log on to the new Exchange Server and run the installation setup. Make sure that the account is a Domain Admin, Exchange full Administrator and a member of the administrators group in the NT domain.
