Re-create the authentication database. On a Windows NetWorker server, this is done by reinstalling the NetWorker package with a brand new authentication files.

Steps:

1. Uninstall NetWorker from Programs and Features.
2. Rename 'C:\Program Files\EMC NetWorker\nsr\authc-server'
3. Reinstall NetWorker over the existing file structure. A new authc-server directory will be created.

This does not pose any risk to your existing NetWorker configurations or backups; however, you will need to recreate the NetWorker administrator password. If you previously had additional NetWorker users configured or external authority (AD/LDAP) integrated, you will need to reconfigure it.
