    Having a client get this error message when trying to do updates. We suspect that updates are needed on the system as they are having some VPN connectivity issues.

    I found a quick simple and easy fix.. Point the computers DNS to Google. It seems that for whatever reason that the local computer can't seem to resolve MS updates. Pointing to resolves this.

    Google Search for error.

    Microsoft KB on the error

  • Service Provider

    What does nslookup tell us? Do normal websites resolve when pointed to the internal DNS server?

  • What if they run this

     %windir%\system32\wuauclt.exe /detectnow

  • If the force update doesn't work,

    Try the below from here

    Method 2: Steps to erase Windows Update history
    Note:Erasing the windows update history will just remove the entries of the updates and not really the updates itself.

    b. Copy/paste the below command:
    c. net stop wuauserv
    d. And select OK.
    e. Wait until confirmation that the service is stopped.
    f. To delete the file, copy the following command in the command prompt:
    g. del %systemroot%\SoftwareDistribution\DataStore\Logs\edb.log
    h. You can also delete it manually by going to the location in windows explorer.
    i. you can restart the service with this command:
    j. net start wuauserv

  • EDIT: just realised that the PC in the OP isn't using WSUS (I'll leave my reply anyway)

    SolarWinds make a handy tool for diagnosing endpoint WSUS issues

  • Just because it's always good to ask... Has the PC been swept recently for malware?

  • I see this happen on my servers a couple of times a month. Basically it happens when one of our local DNS servers are down for maintenance. Usually a couple of minutes wait or a reboot of the server fixes the issue.

  • @nadnerB good question - no it hasn't. WebRoot is installed, but there is always that chance something got through.

    Thus far - the system has been fine since the change and updates
