    We have a WSUS 3.0 SP2 server running on Windows 2008 R2, with 25 replica servers pulling from it and they are all the same WSUS version 3.2.7600.226. One of the replica servers has stopped running its Synchronization each night, all other synchronizations leading up to it are successful, but it just stopped one day and has not run since.

    I have attached a picture of the synchronizations, there are no failed syncs to check the details, it appears that they are not even starting. I have checked the schedule and it is set properly, nothing has changed there and nothing has changed on the primary server as far as I am aware. If I try to run a manual Sync, it just sits at 0% and does not proceed. I wanted to check the logs for the sync schedule, but wasn't sure where these are actually located?

    Any ideas are greatly appreciated.

    Hi,

    According to your description, my understanding is that single downstream WSUS server failed to synchronize from upstream server, is that correct?

    If that’s the case, I suggest you firstly check whether upstream server is correctly specified, then check whether the upstream server is resolvable by ping its FQDN.

    If the issue persists, please follow troubleshooting steps within this article below:

    In addition, WSUS logfiles can be found under %ProgramFiles%\Update Services\LogFiles.
