Next, you may want to modify the settings of the newly created EASA service. The most common modification is to change the user account, under which the service will run. The configuration varies between Windows and Linux computers.

By the default configuration on a Windows computer, the EASA service will start automatically and will log on using the Local System.

Configure the service to log on as the user account that will communicate with a Compute Server as follows:

1. From the Start menu, select: Settings > Control Panel
   • First double-click on the Administrative Tools icon
   • Then double-click on the Services icon
2. Double-click on the 'EASA' line in the 'Services' panel causing a 'Service' window to pop up.
3. Select the 'Log On' tab
4. Click the 'This account' button
5. Enter the chosen account name and password

When specifying the Account to run the EASA Service setting, be sure to use the correct syntax, especially for domain user accounts. The safest approach is to use the Browse button to locate and select the account.

1. The 'Local System' account must not run an ' Excel Server as a service' (see Configure EASA service to run as a non-SYSTEM user)
2. Finally click on OK

The EASA service must be configured to log on as a specific user account prior to installing the EASA Client. Otherwise, a local EASA Client will not function properly on the EASA Server. This issue only pertains to the EASA Client on the same machine as the EASA Server. The EASA Client will install and function properly on all other client computers, regardless of the Log On method of the EASA Service.

By default on a Linux computer, the EASA service is set up to start automatically and run under the 'root' account.

Configure the EASA service to run as a particular user as follows:

1. Configure the service to run as the new user via RUN_USER attribute:
   • In <EASAROOT>/tomcat/bin/easa.conf set RUN_USER=user1
2. The user account that runs EASA must have write permission to all folders under <EASAROOT>/
