Fixing “File cert verification failed” errors in WSUS

InfoButtonHere’s a heads up on a nice article I found over on the TechNet Wiki today. This is one written by Microsoft’s own Yuri Diogenes and it talks about some potential causes for an issue where WSUS syncing fails and a “File cert verification failed” message is logged in the SoftwareDistribution.log:

Consider the following scenario:

- A WSUS replica is trying to synchronize and it is not able to.

- In the SoftwareDistribution.log for the WSUS replica server, the following information appear:

WsusService.11 CabUtilities.CheckCertificateSignature File cert verification failed for e:\WSUS\WsusContent\92\8C44A8CC479069434AFB1EC6651C4F4E88217A92.exe with 2148204800 Warning WsusService.11 ContentSyncAgent.ProcessBITSNotificationQueue Invalid file deleted: d:\WSUS\WsusContent\92\8C44A8CC479069434AFB1EC6651C4F4E88217A92.exe
Info WsusService.11 EventLogEventReporter.ReportEvent EventId=364,Type=Error,Category=Synchronization…
