One of our Nimesa customers faced this issue in his environment, That organization has Active Directory and they use AD for all the Machines in their datacenter.
While taking the backup using Nimesa the user got The security database on the server does not have a computer account for this workstation trust relationship error, he cannot able to connect to the machine through RDP.
We connected to the machine from console
- Login with local admin or user with admin rights
- Join the computer to the WORKGROUP
- Re-join back to DOMAIN

The above steps solved the log in problem and admin can able to run backups from Nimesa.
