Wsus 3 0 sp2 clients not updating
SCUP requires a signing certificate to sign updates digitally that it publishes.This digital signature enables clients to verify the integrity of the updates.Use this option if Configuration Manager manages software updates in your organization’s environment.Trusted Publishers options, shown in Figure 3-3, enable you to configure which publishers SCUP trusts.Config Mgr Server options, shown in Figure 3-2, enable you to configure how Updates Publisher 2011 interacts with System Center 2012 R2 Configuration Manager to publish software updates.You should always publish to the top-level WSUS server in your Configuration Manager environment because this ensures that all child sites have access to SCUP published updates.
After the software updates are imported into the repository, you can publish or export them to an external catalog. When you publish a software update to WSUS or Configuration Manager by using SCUP, you can choose to publish all content associated with the software update or just publish meta-data associated with the update. You use the Publications workspace to publish a publication to an update server, export a publication, and remove software updates from a publication.Depending on the details of your SCUP deployment, you can choose to publish updates to a WSUS server or to a WSUS server integrated with Configuration Manager.Update Server options, shown in Figure 3-1, enable you to configure whether Updates Publisher 2011 publishes software updates to a WSUS update server and whether the update server is local or remote and to specify the certificate that Updates Publisher 2011 uses to publish software updates.This requirement is not a problem if you have obtained the certificate from a CA that client computers trust but requires special configuration of clients if you use the self-signed certificate.When you obtain a signing certificate for Updates Publisher 2011 from a CA, ensure that it has the following properties: If you use a self-signed certificate, export the self-signed certificate from the server that hosts SCUP by using the certificates snap-in of the Microsoft Management console.
That’s when products such as System Center Updates Publisher and System Center 2012 R2 Configuration Manager are useful.
