"Devices trying to synchronize updates from Microsoft Updates using Windows Server for Update Services (WSUS) might fail to complete the synchronization process. Microsoft has confirmed a widespread issue in Windows Server Update Services (WSUS) that prevents organizations from syncing with Microsoft Update and deploying the latest Windows updates. Windows Server Update Services (WSUS) is a Microsoft product that allows businesses to manage and distribute Windows updates to computers within their network. By default, WSUS synchronizes with Microsoft Update servers once a day, when it downloads the latest metadata on available Windows updates. Since last night, Windows admins have reported that WSUS synchronization is broken, with event logs showing "A connection attempt failed" or .NET errors stating, "The operation has timed out," when syncs were attempted. Microsoft has now confirmed the synchronization problem in WSUS and said that they identified a "problematic update revision in the storage layer" that is causing the issue. As a result, updates cannot be deployed using WSUS or Configuration Manager," reads a Microsoft advisory shared with BleepingComputer. "Is anyone having synchronization issues with their WSUS server? I started having issues last night and still cant get it to sync this morning. Lawrence Abrams Lawrence Abrams is the owner and Editor in Chief of BleepingComputer.com.
