WSUS Server :

1. How to force an AU Client to detect and download approved updates from a WSUS Server?

A. Run this command from Command prompt at the AU client :

wuauclt.exe /detectnow

2. Verify if the AU Client is checking in with WSUS Server?

A. Scan thru %WinDir%WindowsUpdate.log for the following entries :

(ie. C:WindowsWindowsUpdate.log);

3. What is the file %WINDIR%SoftwareDistributionReportingEvents.log used for on WSUS clients?

A. It appears to be where the WSUS client records update activities and results.

To display the current status of the Automatic Updates status

There are actually two registry keys that are used when specifying a WSUS server.
Both of these keys are located at:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdate.
This registry key holds a string value which should be entered as the :
WSUS server’s URL (example: http://servername).

All command line options :

/DetectNow
/ReportNow
/RunHandlerComServer
/RunStoreAsComServer
/ShowSettingsDialog
/ResetAuthorization
/ResetEulas
/ShowWU
/ShowWindowsUpdate
/SelfUpdateManaged
/SelfUpdateUnmanaged
/UpdateNow
/ShowWUAutoScan
/ShowFeaturedUpdates
/ShowOptions
/ShowFeaturedOptInDialog
/DemoUI
!

To reset the Automatic Update client Open a command window :

Type wuauclt.exe /resetauthorization /detectnow

Wait 10 minutes for the detection cycle to finish.

To troubleshoot the Automatic Update client Open a command window :
Type: reg query HKLMSOFTWAREPoliciesMicrosoftWindowsWindowsUpdate

You should see output like the following if the client has been configured to get its updates from
a WSUS server:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdate
WUServer    REG_SZ  http://WSUSServerName
WUStatusServer      REG_SZ  http://WSUSServerName
HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdateAU


This works well. Save to a .cmd or batch file and run.

net stop wuauserv
REG DELETE “HKLMSoftwareMicrosoftWindowsCurrentVersionWindowsUpdate
Auto Update” /v LastWaitTimeout /f
REG DELETE “HKLMSoftwareMicrosoftWindowsCurrentVersionWindowsUpdate
Auto Update” /v DetectionStartTime /f
Reg Delete “HKLMSoftwareMicrosoftWindowsCurrentVersionWindowsUpdate
Auto Update” /v NextDetectionTime /f
net start wuauserv
wuauclt /detectnow

Report Now Steps :

wuauclt /a /detectnow
and then
wuauclt /r
for an update to occur
