WSUS replica server fails to synchronize with the master. WSUS infrastructure consisting of master WSUS server and one or more downstream replica servers may, at some point, stop synchronizing successfully. If you enable driver updates in your WSUS infrastructure, this sync issue may happen as quickly as 2 weeks after the WSUS server build. Most frustratingly, running index defrag on WSUS database or/and running WSUS Cleanup Wizard do nothing to fix the issue. Symptoms. When you attempt to synchronize downstream server with the master, sync progress goes to 9x% (9. It eventually errors out with a SQL exception error, typically this is a timeout. You can see this message by clicking on the Details link in the sync run details, in WSUS console.

Time Out Approving Updates In Wsus Update

Time Out Approving Updates In Wsus School

On the replica server(s), run WSUS Server Cleanup Wizard (from the WSUS console; leave all checkboxes checked in default configuration). If you have multiple replicas. I have several updates that were declined within. WSUS server times out trying to replicate from the master server. TdsParser timeout issue in WSUS. Too many declined updates break WSUS replication. Windows Server Update Service (a.k.a. WSUS) is Microsoft free tool they provide for deploying patches and updates. In my experience this tool is pretty much used by. So I have installed a new instance of WSUS on a 2012R2 system. The WSUS server will be serving about 350 systems (servers+desktops+laptops) total. It is running in a.

Sql. Exception: Timeout expired. Check out this article first to see if driver update problem applies to you. Cause. If this is specifically a Tds. Parser timeout, the issue is that your WSUS system has too many hidden updates in the database, and from the looks of it, WSUS server is trying to do some XML parsing of hidden updates and is not able to process all updates for replica sync. Hidden updates = declined updates.

Number of declined updates mushrooms in WSUS databases if, ironically, you run WSUS Cleanup Wizard, which marks superseded and expired updates as declined. Declining unneeded updates is a good thing but it has this interesting side effect of breaking WSUS replication. To confirm that this is indeed the issue, on your replica WSUS server, open SQL Server Management Studio (this article has information on how to install SSMS on WIDS WSUS database server), open Activity Monitor, expand expensive queries pane, and trigger manual synchronization run. You should see two RUNNABLE processes, one of which will be running under NETWORK SERVICE identity and showing as coming from wsusservice. Right- click on this process and click Details. You will see this command: SUSDB. Get. Updates. For.

Microsoft’s primary tool for deploying updates is the Windows Server Update Service (WSUS). What some administrators.

Bulk. Hide. In. Replica. Sync; 1. Next, run this statement above in SSMS new query window. You should get a response back from SQL very quickly (a couple of seconds) but it will contain several tens of thousands of results – possibly 5. If you don’t see any other queries in Activity Monitor, and your CPU utilization goes up and flattens out, taking up about one core (so ~2. CPU utilization on a 4- core system), and stays at that level for a few minutes, the article applies to your situation. The issue is that SQL server returns requested results quickly, but then WSUS server tries to do something with associated XML definitions (explaining why there are no subsequent queries and seemingly high CPU utilization) and times out.

Running this query below will also return a large number of matches, possibly as high as 5. SELECT * FROM tb. Update WHERE is. Hidden = 1. Temporary Fix. Before putting in a more permanent (and irreversible) fix, try running this query on the replica WSUS server that can’t synchronize successfully: UPDATE tb.

Update SET is. Hidden = 0 WHERE is. Hidden = 1. After running this query, perform a manual sync on the replica WSUS server. Most likely, your replication will succeed this time, proving further that the issue is the number of hidden/declined updates in the system. Unfortunately, you would only be able to synchronize once using this method.

The first synchronization run will synchronize is. Hidden flag in the tb. Update table from the master WSUS server, and the following replication runs will fail with the same Tds.

Parser issue. Permanent Fix. Permanent solution involves reducing the number of hidden updates in the database. You need to manually delete definitions of hidden updates. Use the following queries to do this, and don’t forget to do it on all WSUS servers (assuming each WSUS server has a WIDS or Sql. Express database) in your infrastructure. Revision where Local.
