Host credentials when using DBControl 10gR2 on WINDOWS

Problem:
Going to Preferences > Preferred Credentials > Host > Set Credentials and
entering the correct username and password also results in:

Error Connection to as user failed: ERROR: Wrong
password for user

Cause:
The Windows operating system user does not have the required 'Log on as a
batch job' system privilege.

The 'Log on as a batch job' system privilege is required by the user whose
credentials are used for the preferred credentials for a Host. The user
needs to be able to log on as a batch job in order to execute jobs such as
backup jobs in the background.

Solution:
To implement the solution, please execute the following steps:

1. Go to Start > Control Panel > Administrative Tools > Local Security Policy
2. Open Security Settings > Local Security Policies > User Rights Assignment
3. Double-click on Log on as a batch job from the list of privileges in
the right pane.
4. Click on Add User or Group ... and enter the name of the OS user whose
credentials are being used as the preferred credentials for the host.
5. Click 'OK' twice.
6. Retry the preferred credentials test for the user at Preferences >
Preferred Credentials > Host > Set Credentials
