Networking And Gateways :: TNS Listener Service Won't Start After Changing (Logon As) Setting

One of our requirements is to secure the listener and other Oracle services by running them as a local OS account rather than as LocalSystem on the server.

I created a local OS account (assume it's named oracleuser), assigned it to the User and ORA_DBA groups on the server, and then I went to the Local Policies and added oracleuser to "Deny log on locally" and "Log on as a service".

I opened up the Services utility and stopped the four Oracle services we have running (OracleMTSRecoveryService, xxx_home1iSQL*Plus, xxx_home1TNSListener, and OracleServiceMYDB). I changed the "Log on as" for each service to oracleuser with its password (copied and pasted so I know there are no typo's), and restarted the services.

All the services except the listener started up. Attempting to start the listener caused the following error:

"The xxx_home1TNSListener service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service."

I tried rebooting the server and had the same result.For now just the listener service has been switched back to logging in as LocalSystem while the other services continue to use the local OS account and the database seems stable, but I do need to figure this out.
