ERROR_CLUSTER_NO_RPC_PACKAGES_REGISTERED - 5081 (0x13D9)
No authentication package could be registered with the RPC server.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_CLUSTER_NO_RPC_PACKAGES_REGISTERED indicates that the Remote Procedure Call (RPC) server failed to register any authentication packages. This can occur in a Windows environment where cluster services are involved, as it pertains to the RPC infrastructure used for inter-node communication.
Error Details
This specific error is related to the Cluster Service component of Windows and is indicative of an issue with the registration process of RPC authentication packages. These packages are essential for secure communication between nodes in a clustered environment. The absence of registered packages can lead to failures in establishing or maintaining connections, impacting the overall functionality of the cluster.
Usage Context
This error typically manifests when attempting operations that require inter-node communication within a Windows Failover Cluster. It is not specific to any particular file system operation, access control mechanism, parameter validation, data integrity check, resource limit, or unsupported capability but rather pertains to the RPC infrastructure's ability to authenticate and establish secure connections.
Developer Interpretation
Developers should interpret this error as an indication that there is a problem with the registration of authentication packages required for RPC communication. This could be due to misconfiguration, missing components, or issues within the cluster environment itself. The error suggests that the necessary security mechanisms are not properly set up, leading to potential security vulnerabilities and operational disruptions.
Related Errors
ERROR_RPC_SVC_STOPPED(2180): Indicates that the RPC service has stopped.ERROR_RPC_NOT_PRESENT(2179): Indicates that the RPC server is not present on the node.ERROR_RPC_SERVER_UNAVAILABLE(2163): Indicates that the RPC server is unavailable.
FAQ
Q: What does this error mean?
A: This error indicates a failure to register authentication packages with the RPC server, which can disrupt inter-node communication in a Windows Failover Cluster.
Q: How common is this error?
A: The frequency of occurrence depends on the specific configuration and usage context. It is more likely to occur in complex cluster environments where multiple nodes are involved.
Summary
The ERROR_CLUSTER_NO_RPC_PACKAGES_REGISTERED (5081) error signifies a failure in registering authentication packages with the RPC server, which can impact inter-node communication within a Windows Failover Cluster. Developers should ensure that all necessary components and configurations are correctly set up to avoid this issue.
