Window Defender. What is 0x800106ba? Is it important?

Discussion in 'Windows Vista Security' started by tomoedinburgh, Oct 26, 2008.

  1. Everytime I start, Windows Defender says

    Failed to intialize 0x800106ba
    A problem caused this program's service to
    stop. To start service, restart or search
    help and suppot to start it mannually

    What is this 0x800106ba? Is it important?:shock:

    Restart does not solve this.
    Could anyone tell me how to fix it?

  2. Hi SIW2

    thank you, I remember you. You helped me previously.
    Well, i visited the site and tried all three there.
    I could not uninstall the defender. it was not in the "program"
    but I installed successfully the latest version of WD from the site.
    However, this did not solve the problem.

    I typed in the patches in the option three. Some went in
    some came back saying "problem 0x800106..."

    Still, each time I restart, WD says "cannot initialize 0x800"

    The voice of HAL says "Sorry, I cannnot do it"....
    I dont know what more I can do with this...

    Always worth checking for malware, you may like to download and sca
    with the free

    '' (

    Suggest you try a system restore to a point before Defender stoppe

    If you are still having problems, run a system file chec

    and if necessary, do a repair install ( you need the proper Microsoft
    installation dvd to do this

    If you could also add your system specs. that would be useful - go t
    User CP at the top left of this page to add them

    Hope it help

  4. 0x800106ba RPC_S_Server_Unavailable
    This is a BITS or COM related issue.

    Have you diabled any services ?
    Is KB939159 installed ?
    Is Vista SP1 installed ?
    What is the installed security software [antivirus/security suite/etc] ?

    BTW, you can NOT uninstall WD in Vista, you can only disable the Service
    that it's dependent upon thereby stopping WD from functioning.

  5. Hi

    many thanks for the suggestion

    I deleted some files which I believed were just duplicates and I a
    I did something wrong there.. just a guess but they coincide

    No, I have not took in SVP1. I read reviews and pretty much convince
    that it is more trouble than it is worth. But do you think downloadin
    the service pack solve this problem

    Could you possibly tell me how serious having this 0x80010
    Is it in anyway putting my PC in danger? Or is it just a nuisance

    Let me get back to later with this upfate K something..

  7. Hi again

    I regulary delete Shadow Copy and do registory Cleaning. Can I still
    the system to a few weeks back?

    I also worry if I do this system restore I would lose change I made and
    softwares I downloaded since. How does the system restore affect PC?

    Hi tomo...,

    You probably don't have restore points going back weeks.

    If you have the proper MS installation dvd , you do a repair install
    which will replace replace all the Vista files , but should not affect
    your data and programs.

    If you have some ghastly "recovery" disc from the manufacturer - it
    probably only allows you to put the system back to how it was when you
    got your machine. You would need to transfer all your stuff to an
    external hd first and then back after and reinstall all your programs.

    It would help if you Click User CP at the top left of this page and
    input your system specs.

    Hope it helps

  9. If you have some ghastly "recovery" disc from the manufacturer - it
    Just picking some nits - it is often misunderstood what the
    difference is between restore and recovery. Recovery is
    meant to recover from some unfortunate thing. It implies
    the end state is as it was just before the incident. Restore
    is the one that gets you the sometimes less desireable "as
    new" condition.

    When using either process, it is best to read the documentation
    to see what will actually be done. Misuse of terms is rampant
    because nobody cares about language anymore.
    Yes, a real PITA.
    I can't see what you refer to. I click and I click anyway and nothing
    seems to happen.
    FromTheRafters, Oct 28, 2008
  10. Yeah, I'm sorry too.

    Microsoft didn't actually get it wrong when they named the
    restore facility, it does get you back to a previous "as new"
    state for the things under its purview. If they called it system
    recovery people should expect it to do a lot more than it does.

    Restore is OS independent. Recovery would require some backup
    plan or at the very least some knowledge of the OS and user data
    that needs the recovering.

  11. dear mow green

    I checked my updates and i dont think I have KB939... the one you
    mentioned. What sort of update is this?
    tomoedinburgh, Oct 29, 2008
  12. dear S1W2

    About SP1. It says you need 4.5G free space to install.
    Does this mean SP1 occupy that amount of HD once installed?
    Or you need that to install but the pack does not take up that much?
    Do you know how much space SP1 take up?

    I read reviews and they say the improvememts are marginal.
    They are like, "well, it does not hurt" sort of reception.
    Could you tell me how one can beneft from downloading SP1,
    apart from having a piece of mind, so to speak?

  14. Hi SIW

    Thanks for the advice. I am giving SP1 a serious thought
    The problem with my PC now is the Explorer
    It very easily freezes and gets glazed over and says "Explorer is no
    responding". It was not like this before, but I am not sur
    if it was anything to do with the Windows Dedender giving
    me this "Error 0x800106" sign. (In fact, Security says Defende
    is on and working, but when I click the icon or every tim
    I restart it tells me about the error

    Do you think SP1 might solve this problem

    BTW, I could not install the BK939.... that MowGreen suggested
    It came back saying "it does not apply to your PC
    tomoedinburgh, Oct 30, 2008
  15. Problem solved! Well, sort of

    Dear SIW

    Im happy to tell you I got rid of the error message
    I installed this update that finishes with 09
    (consequently i joined something called Spynet club
    considering the time i wasted solving this error proble
    it was a hef entrance fee, but im glad now)

    Thank you very much for your help

    However, this problem with the Explorer persists
    So, do you think SP1 helps this crash problem?

  16. 'Cleaning' the registry is the most likely cause of this issue. If you
    used an automated tool, then restore it's backup.
    If you did it manually, then you *should* have exported the reg
    key/subkey prior to 'cleaning' it.

    Cleaning the registry only needs to be done to ensure malware is not
    loading from it. Otherwise it's gun + shoe = ouch !!!

    Did you download the version of KB939159 meant for *your* system ?
    There are 2 versions, x86 and x64, linked from the KB article.

    I repeat:

    What is the installed security software [antivirus/security suite/etc] ?

  17. Hiya

    I always have the windows Defender and Wall on naturally.
    But I also have this software called Spyware Terminator
    which I chose randamly by googling. It works but I have no
    idea how or if it is effective. I have never read a review
    on this software. One thing I dont like about this software
    is the full scan takes 3 hours to complete. I have never got
    virus if I trust what all those softwares say. Do you think I should
    something else to defend my PC?

    Hi tomo,

    Don't know much about Spyware Terminator , but I wouldn't have the
    patience for such a long scan.

    You really need an antivirus app. Avast free home edition is liked by a
    lot of members here, you might try that instead. It helps guard against
    malware and rootkits too. Read the help section to set it up how you

    You probably don't need the Vrdbs function, if so, right click the ball
    on the left in the notification area, and select disable , then merge
    with main icon.

    'FREE antivirus software for Windows with anti-spyware - avast! Home
    Edition' (

    Ccleaner is another free app. that helps reduce the clutter on your pc
    and remove unpleasant cookies - again check out the help file to set up
    how you want ( uncheck the Windows Defender option under the
    Applications tab )

    'CCleaner - Downloading Slim...'

    I use McAfee site Advisor, which attaches to your web browser and warns
    you if it thinks a site is dangerous - it's free from

    'Protection from Adware, Spam, Viruses, Online Scams | McAfee
    SiteAdvisor' (

    You might also try The Vista Firewall Control , free from

    'Vista Firewall Control : Sphinx Software'

    Once it is trained , it provides some protection against outbound
    connections, and also reduced my start up time by a few seconds.

    Hope this helps


    If you suspect something may have got past Avast and Defender, then
    scan with this free app. ''
