Sollte bei der SUP/WSUS-Synchronisation mit Microsoft der folgende Fehler auftauchen
“Sync failed: UssCommunicationError: WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. —> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.~~at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request). Source: Microsoft.SystemsManagementServer.SoftwareUpdatesManagement.WSyncAction.WSyncAction.SyncWSUS”
so kann es helfen, die aktuellen Root-Zertifikate von Microsoft zu installieren: http://support.microsoft.com/kb/931125/en-us
