Forefront Client Security updates hogging processor RRS feed

  • Question

  • We're having a recurring problem with PC's performing sluggishly (presumably) while they are downloading / installing updates for Forefront client Security.

    Goes something lie this:
    Users will call in complaining that their PC is slow.  During troubleshooting, our helpdesk guys find that the process "wuauclt.exe" is consuming 95-100% of the processor.  If they disable Forefront, the offending process stops, and the issue does not reoccur for several days.  If they later re-enable forefront, the issues happens again, usually within 24 hours.  

    Waiting it out has not worked (1-2 hours of unusable computer is not acceptable to the users).  Turning off forefront allows users to work, but running with no anti-malware is not really a viable long term solution.

    Any suggestions?

  • Hi

    Wuauclt.exe is the Windows Update process.

    1) If he is going to 100% check your update settings. If get the update form MS direct check your firewall settings?

    2) Remove all file from : C:\WINDOWS\SoftwareDistribution\. You need to stot windows update. For this you can type "net stop wuauserv" at a command prompt. Do a reboot after the deletion.

  • Thanks for your response.

     

    The update settings are set via GPO to use our WSUS server.  (WSUS ver 3.2.7600.226, windows update version 7.4.7600.226)

    Those two KB articles do not appear to apply to us, as we already have update 927891 installed. 

    I will try deleting the files in softwaredistribution and see if that helps.

     

     

    Thanks,

    Peter

  • Hi

     

    We have a similar problem on our sites. What i have noticed that the only PC's having problems are P4's Single processor. No Duo Cores.

    We have Reformatted these PC's and after a certain time period it slows the systems down again. We also run WSUS Servers that pushes the updates threw.

    In task manager we noticed WUAUCLT.exe thrashing the CPU to 94 -99%. Making it inpossible for the users to work. However after you kill the process it is stable and working fine again. If you manually force the WUAUCLT /Detectnow it runs at 30 -50% and is stable.

    It appears to happen around a certain time period as well (usually just after 10am) Which is when the WSUS is pushing threw updates at our dealerships.

     

    Any ideas or Help will be appreciated.

     

    What we have tried.

    Installed latest updates.

    Installed

    WindowsXP-KB914882-x86-ENU
     
    Reloaded PC's
     
    Many Thanks .
