23:05:49.230 UTC Warning WsusService.33 WebServiceCommunicationHelper.ProcessWebServiceProxyException ProcessWebServiceProxyException found Exception was WebException. To prepare for this date, we will turn off the endpoint at periodic intervals, occurring on:ĭuring the shutdown, if you attempt to sync WSUS 3.0 SP2 it will not succeed, which results in the following error message in your log file: WSUS 3.0 SP2 will continue to sync updates with upstream server after October 31, 2021. As part of your transition, you can setup a new top level WSUS running on Windows Server 2012 or newer, then use WSUS 3.0 SP2 as a downstream server. Additional guidance (added July 16, 2021) As a result, any organizations still using WSUS 3.0 SP2 must migrate to a currently supported version of WSUS by October 31, 2021. WSUS 3.0 SP2 does not support this newer protocol. Microsoft is transitioning all endpoints to the more secure TLS 1.2 cryptographic protocol. If any component is out of date, or not properly configured, the communication might use an older, less secure protocol. The protocol that is used for a given connection depends on the capabilities of the associated components. WSUS relies on several different components for secure communication.
It is, however, still possible to synchronize and download updates from Microsoft using WSUS 3.0 SP2. Whether being used standalone or as a component of other products, it provides a variety of useful features including automating the download and installation of Windows updates.Įxtended support for WSUS 3.0 SP2 ended on January 14, 2020, in alignment with the end of support dates for Windows Server 2008 SP2 and Windows Server 2008 R2. WSUS is key to the Windows servicing process for many organizations. On October 31, 2021, Windows Server Update Services (WSUS) 3.0 Service Pack 2 (SP2) will no longer synchronize and download updates. Update : To provide organizations more time through the upcoming holiday period to complete necessary migrations, we are extending the deadline for organizations still using WSUS 3.0 SP2 to migrate to a currently supported version by January 10, 2022.
