Windows Update Not Working on 3 WS2012R2 Machines? RRS feed

  • Question

  • Hi Guys,

    This is the first time I've come to the forums for help.

    If anyone else has any experience with a similar issue and has a fix it would be much appreciated.

    I've got a customer server setup that has WS2012R2 STD running as a host, for HyperV and Backup purposes. But I'd still like to keep the host updated,

    2 of the HyperV guests are WS2012R2 STD machines also.

    None of these 3 units are getting Windows Update's, I've checked all firewall rules, and there is no issues there,

    However I came across a powershell script that I could use that checks outstanding updates and downloads + installs via PS. But this is a manual solution and needs to be run again from the beginning after every restart.

    I know it's a very open ended question but any assistance or suggestions are greatly appreciated.

    Thanks in advance

  • What's in windowsupdate.log file ? Is the server able to scan for updates ?

  • Hi Arnav,

    The log from the last time it tried to update is following.
    Prior to this the last check was 2016-09-28.

    I have had a brief look over it and can see that it has had trouble connecting but I'm not sure what the recommended fix for this situation is, any help is appreciated.

    Please let me know if you need any further information, hopefully the issue is identical for all 3 installations.

  • HI Gpanucci,

    I'd recommend following:

    first we need to know some information:

    1- is your customer getting updates from control panel like going manually and checking for updates or he has SCCM or WSUS in place?

    2- go to this Microsoft Article kb/885819 under workaround section and in your customer's company firewall\proxy configuration make sure the websites mentioned are excluded and you might get help from company security team on that.

    3- restart wuauserv service.  (to set a marker in the log file and please write down exact time in HH:MM)

    4- check for updates from control panel

    5--send me the whole C:\windows\windowsupdate.log file


    Microsoft CTS

  • Hi Mahmoud,

    Thanks for your response!

    In response to your questions

    Control Panel - Doesn't find any updates after hours of searching

    SCCM - No

    WSUS - No

    2. I had wildcard exceptions on most sites listed in that KB, but I have now explicitly copied each one individually.

    3. Done. 5.12pm AEDT

    4. No luck still :(

    5. https://www.dropbox.com/s/qf5y901eecpymle/WindowsUpdate.log?dl=0

    Hopefully this can shed some light on the issue?

  • Hi Gpanucci,

    here you go:

    - from windowsupdate.log file apparently after service starts it fails to detect for updates with following error:


    WARNING: Failed to find updates with error code 8024a008


    BUT what is more important is following part:


    149 [AU_UNABLE_TO_CONNECT] 102 {00000000-0000-0000-0000-000000000000} 0 0 AutomaticUpdates Failure Software Synchronization Unable to Connect: Windows is unable to connect to the automatic updates service and therefore cannot download and install updates according to the set schedule. Windows will continue to try to establish a connection.


    so i think it's clear now ? it's unable to connect! 

    you can take it up with the network team to troubleshoot or you can do following also if you want further in depth troubleshooting:

    1- download Microsoft network monitor 3.4 to this affected server

    2- start capture

    3- restart wuauserv service

    4- check for updates manually

    5- once you get error stop capture.

    above steps should be done closely meaning don't allow much time between the steps.

    send me the windowsupdate.log file as well as the capture file after you save it.

    note: in previous log file that you shared it seems you kept restarting wuauserv service multiple times. please don't do this next time.

    Thanks and hope this helps

  • Hi Gpanucci,

    Please check if after doing the following things could help:

    1. Run windows update troubleshooter on the problematic machines, it may help solve general issues;

    2. Reset windows update components:


    3. Check the version of the windows update agent, if it's not the latest one, please update it:


    4. Clear SoftwareDistribution folder in C:\Windows\SoftwareDistribution:

    1) In cmd, run net stop wuauserv; 2) Delete or rename SoftwareDistribution folder; 3) In cmd, run net start wuauserv;

    After doing the above, check for update again, if still have issues, check the error in windows update log after then.

    Best Regards,
