On each agent computer, the Client Communication Manager (NetIQccm) service and the Client Resource Monitor (NetIQmc) service can run using either the LocalSystem account or a specific Windows user account. Both services must use the same account on any single agent computer. Although the LocalSystem account is used by default in most cases, there are many reasons to use a specific Windows account instead.
You should use a Windows account for the Client Communication Manager (NetIQccm) and Client Resource Monitor (NetIQmc) services if you are:
Sending MAPI email from the agent computer as an action
Enabling the reporting capability option on the agent computer to run reports
Monitoring any Exchange Servers
Monitoring SQL Server in Windows only authentication mode
Running any jobs that require specific privileges or require a user account to perform specific monitoring tasks
Normally, you specify whether you want to use the LocalSystem account or a Windows user account when you install the AppManager agent. You can, however, change this information after installation, using the Services Control Panel program. If you change the account information after installation, be sure to use the same account for both agent services.
For information about Knowledge Scripts that have special requirements and changing the account you use for the agent services, see the AppManager online help.
