Unable to configure reporting

(The password could also be too long, be too recent in its change history, not have enough unique characters, or not meet another password policy requirement.”
Workaround: Format the computer, and rerun Setup.
Central Console support
Description:
The Central Console for DPM supports only System Center 2012 - Operations Manager.
The Central Console is not supported on a Local Management Group (LMG) topology.
If the Operations Manager administrator has not been configured for any of the Central Console roles, they will not be able to view any jobs. To view jobs, restart Operations Manager as an administrator and assign DPM tasks to the administrator user role.
After the Operations Manager Agent is installed on the DPM server, the following registry key settings are recommended so that the data source discoveries can work properly:
Warning
Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Modules\Global\PowerShell] "ScriptLimit"=dword:0000000f
Restart the Health Service (display name: System Center Management) after you change the registry settings. This must be repeated on every DPM server that you are monitoring with Operations Manager.
You cannot restore encrypted files that were protected from an NTFS volume to a Resilient File System (ReFS) volume.
You cannot protect custom volumes with ReFS.
You must enable the Data Deduplication role on the DPM server to protect deduplicated volumes.
If you protect data to tape, the data will be stored in unoptimized form.
End-user recovery for deduplicated volumes will be done in unoptimized form.
If the DPM Administrator Console stops working twice while trying the same jobs and must be restarted, on the third restart DPM will cancel all the running jobs. This may cause the replicas to become inconsistent. You must run a consistency check to ensure that all the replicas are in a good state.
After you uninstall DPM, you must manually disable the deduplication feature in Windows if you do not want to continue using it.
For Live Migration and DPM Scale-Out deployments, the DPM server, Virtual Machine Manager (VMM) server, and Hyper-V hosts should be in the same domain.
All components of the virtual machine should be on one file share.
IPv4 or IPv6 addresses for the storage location file server are not supported.
Secondary protection is not available for virtual machine mobility, scale-out, and deduplicated volumes.
Ensure that all Hyper-V hosts and virtual machines are discovered by the VMM server before you begin creating protection groups.
If you configure page-file exclusion for your virtual machine protection and it was backed up using saved-state backup, after recovery the virtual machine might encounter errors when it starts up. In this scenario, the virtual machine restarts automatically.
If iSCSI target storage provider is enabled on the protected computer, DPM backups of virtual machines that are hosted on Hyper-V clusters might stop. Add the following registry entry to solve this problem.
Warning
Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.
Key HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft Data Protection Manager\Agent\ Value UseSystemSoftwareProvider Data Type DWORD Do the following to protect the Microsoft SQL Server 2012 database:
