WU_E_PT_ENDPOINT_REFRESH_REQUIRED
WU_E_PT_ENDPOINT_REFRESH_REQUIRED indicates stale or incomplete endpoint information. It is usually a service-discovery or configuration condition rather than an installation failure.
Recommended response
- Retry the update scan after the client has regained normal connectivity.
- For a managed update service, verify that the advertised service URLs and client policy are still valid.
- Preserve the preceding log lines: they identify the endpoint provider and the refresh operation that was required.
The endpoint information itself is stale or incomplete
This code is in the Windows Update protocol-talk range and names the endpoint provider plugin, not the update payload. MS-WUSP describes a client-server protocol that discovers and downloads update information through service endpoints. When the provider requires an online refresh, forcing the old URL through repeated SOAP calls keeps using the state that WUA has already rejected.
Preserve the service ID and endpoint URL from Windows Update diagnostics, allow the client to perform its online endpoint refresh, and then create a new search or protocol operation. In managed environments, compare service-location policy and proxy behavior with a known-good device if refresh cannot complete. Hard-coding a previously observed endpoint is especially risky because it bypasses the provider decision represented by this HRESULT.
