I have a few questions regarding WSUS and updating clients.
1. After a client system(WinXP) is configured to use a WSUS via GPO's, if the client goes to Internet Explorer>Tools>Windows Update. Is it accessing my WSUS server or is it accessing the Microsoft Website for its updates?
2. In my WSUS server if I got to Computers>select a computer>then check its status some updates say "Installed" others say "unknown". Is this because it has not recieved the update or is it because the client system hasnt reported back to the WSUS server for details on it?
3. Continuation from question 2. If I look at the list of updates for a specific client computer (WinXP) it also shows updates for Windows 2003 server/Windows 2000/x64 edition updates that are supposed to apply to this WinXP client computer. Is that right? Should it show a list of updates for a computer that shouldnt recieve that update? ie a system that does not have MS Office but the list still shows an Office update is pending?
4. On the Home page of the WSUS server under "Status of Downloads" their is a part that says "Updates requiring files" and the part where is shows Downloading 0.00 MB of 17,515.93 MB. What does Updates requiring files mean? and I have never seen the downloading numbers change. Why?
