Troubleshooting Slow Boot RRS feed

  • Question

  • Hi,

     We are facing slow boot issue in Windows 7 PC's in network. Randomly PC's in the network are taking long time approx 1 hr to boot. When we force reboot these PC's after that it boots fine. This is is happening randomly and not in all PC's. Also the PC's are not fixed. Today the issue comes in some PC's tommorrow those will be different. If we remove network cable at that time then the PC boots properly.

    We have checked group policy processing but found no error. As the PC's are not fixed we cannot enable any debugging.

    Does Windows 7 has any log by default which can help in analysing the reason once PC boots slow.

    Also we are planning to enable diagnostic logging through Group Policy for all desktops. Please let me know if there is any known issue which th the same like slow boot etc.

    The gpo setting is “computer config-admin template-system-troubleshooting and Diagnostic-Windows Boot performance diagnostic”

  • make sure you have the service Superfetch running and next try to speed up the boot with the help of my guide [1]. This trains the advanced prefetcher in Windows 7. This increase the boot performance a lot. All other tweaking tools are useless. Only use this method with this Microsoft Toolkit.

    If this doesn't speed up the boot process, follow my guide [2] to make a boot trace and compress the boot_BASE+CSWITCH+DRIVERS+POWER_1.etl as 7z or RAR and upload it to your Skydrive [3] and post the link here.

    I take a look at the trace, maybe I see what's wrong with your Windows.

  • YOu can try using process monitor -> http://technet.microsoft.com/it-it/sysinternals/bb896645.aspx

    After you have opened it,you can go to the "options" menu and then enable the "enable boot logging".

    It will create a very detailed log on what happens in your machine in the boot phase.

  • What is on the screen when it hangs? (e.g. Starting Windows, Please Wait, Preparing to Configure, Configuring Windows...)

    I have seen some very long startup times when AD Profile is configured to map a drive (connect drive to path). This is usually an "always slow" condition, not "sometimes slow"

    Be sure that KB2775511 (post-SP1 rollup) is applied to clients and DCs. This solves a host of icky WMI wait issues and more. Also consider KB2617858 / KB2505348 (might be in 2775511). If you can't do 2775511 then consider 2675785, 2510636, 2693010. Also 2809808.

    Check your DC resources (memory, page pool, etc.). A periodic restart can be quite cleansing.

    These aren't precise, but could be good indicators:
    - Event 4608 shows up roughly when OS loader starts
    - Group policy starts applying after event 5324
    - Machine authentication at event 5310
    - Domain controller info in event 5308 and 35
    - Event 201 shows up about when 'please wait' appears
    - Events 6006 show up about when ctrl-alt-del appears
    - Event 100 has some good info

    Windows performance recorder and analyzer could be helpful (in ADK for 8.1, which works with Win 7 too).

  • Hi Mark,

    I have checked the links but as the issue is happening randomly in the PC's, we are not able to get to the root of the same.

    I have enabled GPO settings Troubleshooting and diagnostics - Windows boot performance diagnostics, but there is no relevant logs in Diagnostics-DPS and Diagnostics-Performance folders in eventviewer.

    In Diagnostics-Performance the logs are not getting logged regularly even when the system is slow. the logs are getting logged very rarely.

    How to get the informative logs so that whenever the PC is slow we should be able to get some information.

  • Hi,

    We thought about doing that but there is no fixed PC which faces this issue. If a PC faces this issue, once we do hardboot, next time it comes up properly.

  • Hi,

    This can be issue but in that case everytime the issue will happen and for all the users who are having mapped drives to file servers.
