WSUS builds on SUS by expanding the range of software it can update.The WSUS infrastructure allows automatic downloads of updates, hotfixes, service packs, device drivers and feature packs to clients in an organization from a central server(s).SUS ran on a Windows Server operating system and downloaded updates for the specified versions of Windows from the remote Windows Update site which was operated by Microsoft.
Windows Server Update Services (WSUS), previously known as Software Update Services (SUS), is a computer program developed by Microsoft Corporation that enables administrators to manage the distribution of updates and hotfixes released for Microsoft products to computers in a corporate environment.
WSUS downloads these updates from the Microsoft Update website and then distributes them to computers on a network. At first, it only delivered hotfixes and patches for Microsoft operating systems.
System administrators can also configure WSUS to approve certain classes of updates automatically (critical updates, security updates, service packs, drivers, etc.).
One can also approve updates for "detection" only, allowing an administrator to see which machines will require a given update without also installing that update.
Another symptom and a confirmation of the broken IIS hypothesis is a selection of the following warning and error events listed for Windows Server Update Services: service prior to manipulation.
Open Server Manager and remove Web Server (IIS) and Windows Server Update Services roles.Suppose if I prepare a new system and at that moment how can I force client to connect to WSUS and download update.? which generally prompts that new Updates are available etc... An update to WSUS 3.0 SP2 on Windows Server 2008 R2 and Windows Server 2008 (both x64 and x86) seems to break Windows Server Update Services (WSUS) and/or Internet Information Services (IIS) making clients unable to update via WSUS showing error 0x80072EE2.2015-05-27 :157 828 cc8 Service Update Network State Ipv6, c Network Interfaces = 2.2015-05-27 :172 828 cc8 Service Update Network State Ipv6, c Network Interfaces = 1.Windows Server Update Services 2.0 and above comprise a repository of update packages from Microsoft.
