Visiting Event Viewer Custom Views for Server Roles, or hitting the Roles’ list collapse sign (plus sign inside the square) on Server Manager and looking into each role’s events, you’d be surprised to see there’s no recent events or perhaps no events at all listed for Web Server (IIS).This shows that IIS and its pipings are broken and client computers cannot communicate with the server.The first step you need to do is open Local Group Policy Editor.Microsoft is conducting an online survey to understand your opinion of the Technet Web site.
Group Policy is a complicated infrastructure that enables you to apply policy settings to remotely configure a computer and user experience within a domain.
This is required for those Group Policy client-side extensions that do not process on a background refresh cycle but that do process when the user logs on, such as user Software Installation and Folder Redirection.
This option has no effect if there are no extensions called that require the user to log off.
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.
