VNI-2015: authentication error

VN-2015 error occurs because of mismatch of the required privileges of the user. It all depends on the OS and type of USER.
If the OS is MS-NT, please follow the procedure.

If you are a DOMAIN user, the user will need "Logon as Batch Job" privilege. On a Primary Domain Controller, if the account that has "Logon as Batch Job" privilege is not a member of the Local Administrator group, you will also need to grant Logon Locally.

If you are a local NT user, you will need "Logon as Batch Job" privilege.

Verify the Intelligent Agent's startup account is the default SYSTEM.

If the batch job needs to access network resource, you need to verify the user has the access privilege to the network resource.
