Clinet not reporting to WSUS

Hi,

There are many reasons for the systems not reporting to WSUS. There is no single one shot solution but I tried to resolve the same with my experience, Please let me now your experiences with your comments.

1) check the proxy settings :     command proxycfg
result should be as below.

C:\WINDOWS\system32>proxycfg
Microsoft (R) WinHTTP Default Proxy Configuration Tool
Copyright (c) Microsoft Corporation. All rights reserved.

Current WinHTTP proxy settings under:
  HKEY_LOCAL_MACHINE\
    SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\
      WinHttpSettings :

     Direct access (no proxy server).


2) Run the below commands in Command prompt.
net stop wuauserv
regsvr32 /s msxml.dll
regsvr32 /s msxml2.dll
regsvr32 /s msxml3.dll
regsvr32 /s msxml4.dll
net start wuauserv
wuauclt /detectnow
wuauclt /detectnow
wuauclt /detectnow
wuauclt /detectnow
wuauclt /detectnow
wuauclt /detectnow
wuauclt /detectnow

3) restart the system

4) check the registry value (check weather wsus server name is mention)
HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate

If not found or some changes found, then export the registry value from other repoting system and import the same in not reporting system/

5) if still not working then run the Wsus dignostic tool and verify the logs file c:\windows\windowsupdate.log.
    check the error code in google for solution.
