use sqauser as an example of a Server Execution User. This account is automatically added
to the Local Administrators group on each node by the Interplay Engine software during the
installation process.

The Server Execution User is not used to start the cluster service for a Windows Server 2008
installation. Windows Server 2008 uses the system account to start the cluster service. The
Server Execution User is used to start the Avid Workgroup Engine Monitor and the Avid
Workgroup TCP COM Bridge.
The Server Execution User is critical to the operation of the Interplay Engine. If necessary,
you can change the name of the Server Execution User after the installation. For more
information, see “Troubleshooting the Server Execution User Account” and “Re-creating
the Server Execution User” in the Interplay | Engine and Interplay | Archive Engine
Administration Guide and the Interplay Help.
• Cluster installation account: Create or select a domain user account to use during the
installation and configuration process. There are special requirements for the account that
you use for the Microsoft cluster installation and creation process (described below).
- If your site allows you to use an account with the required privileges, you can use this
account throughout the entire installation and configuration process.
- If your site does not allow you to use an account with the required privileges, you can
work with the site’s IT department to use a domain administrator’s account only for the
Microsoft cluster creation steps. For other tasks, you can use a domain user account
without the required privileges.
In addition, the account must have administrative permissions on the servers that will
become cluster nodes. You can do this by adding the account to the local Administrators
group on each of the servers that will become cluster nodes.
Requirements for Microsoft cluster creation: To create a user with the necessary rights
for Microsoft cluster creation, you need to work with the site’s IT department to access
Active Directory (AD). Depending on the account policies of the site, you can grant the
necessary rights for this user in one of the following ways:
- Make the user a member of the Domain Administrators group. There are fewer manual
steps required when using this type of account.
- Grant the user the permissions “Create Computer objects” and “Read All Properties” in
the container in which new computer objects get created, such as the computer’s
Organizational Unit (OU).
- Create computer objects for the cluster service (virtual host name) and the Interplay
Engine service (virtual host name) in the Active Directory (AD) and grant the user Full
Control on them. For examples, see
“List of IP Addresses and Network Names” on
