Hi,

we have a SystemcenterCenter 2012R2 Server based on Windows Server 2008R2.

we have a Problem with one or two deleted Groups on the DPM-Server.

"DPMRADmTrustedmachines"

"MSDPMTrustedmachines"

recreate this Groups and groupmembers (protection Servers) dont help.

Protection agent version: 4.2.1312.0
Error: Data Protection Manager Error ID: 316
 The protection agent operation on GOENT4.local.refra.com failed because the service did not respond.
Detailed error code: Internal error code: 0x8099090E
Recommended action: If you recently installed a protection agent on GOENT4.local.refra.com, the computer may be restarting. Wait a few minutes after restarting the computer for the protection agent to become available. Otherwise, troubleshoot the problem as follows:
1) Check the recent records from the DPMRA source in the Application Event Log on GOENT4.local.refra.com to find out why the agent failed to respond.
2) Verify that the DPM server is remotely accessible from GOENT4.local.refra.com.
3) If a firewall is enabled on the DPM server, verify that it is not blocking requests from GOENT4.local.refra.com.
4) If GOENT4.local.refra.com is a workgroup computer configured to use NETBIOS, ensure that the NETBIOS name of the DPM server is accessible from GOENT4.local.refra.com. Otherwise verify that the DNS name is remotely accessible.
5) If GOENT4.local.refra.com is a workgroup server, ensure that the DPM server has an IPSEC exception to allow communication from workgroup servers.
6) If GOENT4.local.refra.com is a workgroup server the password for the DPM user accounts could have been changed or may have expired. To resolve this error, run SetDpmServer with the -UpdatePassword flag on the protected computer and Update-NonDomainServerInfo.ps1 on the DPM server.
7) Restart the DPM Protection Agent service on GOENT4.local.refra.com. If the service fails to start, reinstall the DPM protection agent.
8) If GOENT4.local.refra.com is configured using certificates, ensure that the DPM CPWrapper service is running on DPM Server and GOENT4.local.refra.com. Also ensure that certificates used by both the computers are valid.

Does anyone know how to proceed here?
