We've installed WSUS on the Server (Window 2008 R2 Enterprise) and deployed for all PC Clients(Window XP, Window 7) in our company. We have not Domain environment. All Clients can update their PC from Server.
However, some Clients change their Computer name or IP Address but WSUS Server can not update those information in WSUS console. Beside that, some Clients re-install OS, so the group policies in the local PC made default (disappear all of config WSUS Client - WSUS were removed), but these PC still exist on the Server.
Summary, WSUS Server can not update the information of Clients on the Server, console WSUS interface have not change when the PC change.
Can you tell me how to solve this problem? Many thanks in advances.
