Loading the syncro history in wsus mmc is very slow and can lead to a timeout [request for server node reset]. In this case delete old history entries:
* Start the SQL server management studio
* —> Databases —> SUSDB —> right click —> New query
USE SUSDB
GO
DELETE FROM tbEventInstance WHERE EventNamespaceID = '2' AND EVENTID IN ('381', '382', '384', '386', '387', '389')
* Action!
