Recurring errors in Event Viewers related to the backup process. The message clearly indicates a security issue … Cryptographic Services was unable to receive an OnIdentity () call on the System Writer object.
This article provides a workaround for Event ID 513 when VSS is running on the latest version of Windows Server.
Applies to: Windows Server 2019, Windows Server 2016
Original Knowledge Base Number: 3209092
On Windows Server, when a task calls a serviceVolume Shadow Copy (VSS) to perform backups, event 513 may be generated:
protocol name: applicationSource: Microsoft-Windows-CAPI2Event ID: 513Task Category: AnyLevel: errorDescription:Cryptographic services crashed even when the OnIdentity () call was being processed in the System Writer object.Details:AddLegacyDriverFiles: The Microsoft Link-Layer Discovery Protocol binary cannot be backed up for an image.System error:Access is actually denied.
This issue occurs because the VSS writer is not licensed to read NT AUTHORITY SERVICE (service account). Likewise, when System Writer starts a cryptographic service and tries to read Mslldp.sys information from this Microsoft Link-Layer Discovery driver, it usually generates an “Access Denied” error.
This moment of logging can be ignored. To prevent this entry from being written to the log, grant the required permission – Microsoft Link-Layer Discovery Protocol Racer (Mslldp.dll) to process the system writer.
Open bigFrom the Administrative Command Prompt window, then run the following command to check your current permissions:
What is cap12 error?
This issue occurs because the VSS system writer does not need NT AUTHORITY SERVICE read permission (service account). With System Writer, it is assumed to be running as a cryptographic service, and reading the mslldp. Sys communication with the Microsoft Link Layer Discovery Protocol driver will treat an Access Denied error that has occurred.
sc sdshow mslldp
Copy the step output line, add a specific value to it with
(A ;; CCLCSWLOCRRC ;;; SU), then move the following command to get permission from adding mslldp .dll:
sc sdset mslldp
run the fanbase command:
sc sdset mslldp D: (D ;; CCDCLCSWRPWPDTLOCRSDRCWDWO ;;; BG) (A ;; CCDCLCSWRPWPDTLOCRSDRCWDWO ;;; SY) (A ;; CCDCLCSWRPD;; S14-1-5-285 1754447212-2405740020-3916490453) (A ;; CCLCSWLOCRRC ;;; SU)

Moving System Restore, Backup Exec, DLO, or NetBackup backups will most likely cause this error, and all subsequent scheduled jobs will fail with the same error.

|Description||Cryptographic services failed while processing the OnIdentity () solution on the system record object.% 1.|
|Event Information||According to Microsoft:
Reason: This event can be logged if encryption services fail while handling the OnIdentity () in the Writer object system.
Workaround: Edit the ACL for a specific registry folder. A component object model (COM) program must have access to specific types of COM + catalog files that are stored in the COM catalog folder. If the default ACL in the COM Folder Gallery in the Windows folder can be described as modified, the Shadow Copy Writer may not work correctly.
To complete this procedure, you must be a member of the closest Administrators group, or you must be assigned the appropriate permissions.
Validation: To be able to run this solution, you must be a member of Local Administrators or a group, clients must be granted the correct permissions.
