Hi all, i have had several hundred machines not report into the WSUS console for a number of months so i have ran the database cleanup and it removed the machines. Unfortunately i cant seem to get them back. I have tried running the following script but they still dont appear. Any ideas?

thanks

%Windir%\system32\gpupdate

%Windir%\system32\net.exe stop bits
%Windir%\system32\net.exe stop wuauserv
%Windir%\system32\net.exe stop cryptsvc
reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate /v SusClientId /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v LastWaitTimeout /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v DetectionStartTime /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v NextDetectionTime /f
del %WINDIR%\WindowsUpdate.log /S /Q
rd /s /q %windir%\softwareDistribution
%Windir%\system32\net.exe start cryptsvc
%Windir%\system32\net.exe start bits
%Windir%\system32\net.exe start wuauserv


sc sdset wuauserv D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)


sc sdset bits D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

Hi,

Run the RSOP.msc and see if group policy is applied.

also share the windowsupdate.log file under c:\windows from any effected system/client.

Hi Santosh, i think i have found the issue the log files shows a different WSUS server. Also when i run the above script and check the windowsupdate.log it shows WSUS SERVER as null. How can i change this so that it points to the new sever. Someone else had set this up before i inherited it. I have about 700 clients and servers that have this issue. Also the script says unable to find the specified registry key value

reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v LastWaitTimeout /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v DetectionStartTime /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v NextDetectionTime /f

thanks

As you said " you have hundreds of machines", so i would like to suggest you to do it through Group Policy.

Move these machines to any/new OU and apply the GPO.

Hi Santosh, GPO is enabled on the root of the client and server OU's but some of the GPO's are blocked. I moved one server and that appeared in the WSUS console. I will investigate the clients as these should not be blocked. Thanks. Its been set up in quite a complicated way with different Tiers from 1 to 4

Hi Santosh, is does WSUS look for clients in the AD or does it scan the network? The GPO for clients seems to be OK.

WSUS knows nothing about active directory.. you use group policy and client side targetting to put the computers in the different groups.  it is a pull vice a push operation
