Changing TM1 services to run as a specific user account on Windows

When you use IBM Cognos Configuration to manage TM1 services, you need to change the default user account that runs the Microsoft Windows services for the TM1® Admin Server and any TM1 servers that you start with Cognos Configuration. By default, Cognos Configuration registers these services under the predefined Microsoft Windows Local System account. However, these services should be changed to run as a specific user account.

Before you begin

Review the required account privileges for using a user account other than Local System account. For details, see User accounts for running TM1 services on Windows.
