WSUS 3.0 SP2 - synchronization with Microsoft Update failed

Question

Hi!
The new installed WSUS Server (W2K8 R2 Std. x64 - full patched, SQL 2008 R2 on remote host) with KB2720211 update.
If I try sync WSUS Server with Microsoft Update than sync failed with error
TypeInitializationException: The type initializer for 'Microsoft.UpdateServices.ServerSyncWebServices.ServerSync.ServerSyncProxy' threw an exception. ---> System.Net.WebException: The remote name could not be resolved: '<wsusserver.LOCAL.DOMAIN>'
at Microsoft.UpdateServices.Internal.ClassFactory.CreateInstance(Type type, Object[] args)
   at Microsoft.UpdateServices.ServerSync.ServerSyncLib.GetWebServiceProxyInternal(UpdateServerConfiguration serverConfig, WebServiceCommunicationHelper webServiceHelper, Boolean useCompressionProxy)

   at Microsoft.UpdateServices.ServerSync.CatalogSyncAgentCore.RetrieveSubscriptionData()

WSUS is configured for using ssl.
Any idea?

Hi,
It is the common issue that may occur when KB2720211 is installed.
WSUS server stops synchronizing with Microsoft Update.
Workaround: remove WSUS , leaving the database on the uninstall.
When removing WSUS , the first screen after asking to uninstall will be what are the items you want to remove with the uninstall. Leave all options UNCHECKED.
Proceed with uninstalling. After finishing, install WSUS again.
Add the role again in Server manager (Windows Server 2008 and Windows Server 2008 R2) or download WSUS 3 SP2 from the following location:
http://www.microsoft.com/en-us/download/details.aspx?id=5216
Start the install and choose the options to connect to the database server or Windows Internal database. As in the example, I am connecting to my Windows Internal Database.
Then choose “use existing database” and proceed with the install.
