Read this article “A WSUS client that is connected to a WSUS or Configuration Manager 2007 SUP server takes longer than expected to finish an update scan” and thought I would promote it as it also affect clients connected to a SUP in SCCM.
From the article:
– A Microsoft Windows Server Update Services (WSUS) client computer is connected to a WSUS or Configuration Manager 2007 SUP (Software Update Services) server.
– The WSUS client computer runs a scan to determine whether an update applies to the client computer.
In this scenario, the WSUS client computer takes longer than expected to finish the scan. For example, the scan may take hours or days to finish. Additionally, you experience the following problems on the WSUS client computer:
– Task Manager indicates high CPU usage for the Svchost.exe process.
– You cannot stop the Svchost.exe process.
On Windows Server Update Services 3.0(applies when using configuration manager as well.)
- Click Start, point to All Programs, point to Administrative Tools, and then click Microsoft Windows Server Update Services.
- Click Options, and then click Automatic Approvals.
- Click the Advanced tab, make sure that the following check boxes are selected, and then click OK:
- Automatically approve new revisions of approved updates
- Automatically decline updates when a new revision causes them to expire
I really recommend that you read the whole article!
