    Everythings Just Stopped... XP Clients, W2k3 DC ridiculous logon times...

    Hi Guys.
    I think this is my first post here, but i have watched for a while.
    Anyway, I'll cut to the chase.

    Last week was the first day back for our kids at our primary school. During the holidays i had re-imaged Every machine in school, upgraded the Nics and memory etc...

    Everything seemed fine untill the first day back. Despite having every machine up and installing software etc the day before (which was hunkey-dorey) everything just ground to a holt as soon at the teachers and kids hit.

    FYI The users have redirected folders, no roaming profiles.

    The XP clients were sat on "Preparing Network Connections" or "applying Computer Settings" for nearly 30 minutes before the logon dialogue appeared.

    Then logon would take a good 20 minutes too.

    When you were in there was problems with shares, they would just come and go.

    The DC its self was a 40 minute wait to logon aswell. and once you were in is was dog slow. Yet memory usage was normal, network traffic and processors were next to nothing.

    The Raid of this server was for some reason rebuilding its self. I sort of put it down to that, and next day everything seemed normal again.

    But today the same thing.............

    When i got the call it was a 20 minute logon to the DC, i rebooted it and could logon as normal, 5 seconds or so but after an hour it all went to pot again.

    A friend thinks its a DNS problem as of late we have had a few cases of Machine names not resolving to the correct IP's

    The Clients are XP SP3 and W7 SP1
    2 DC's running DNS and one of those does the DHCP.

    After looking around on here i have tried adding the domain name to section 15 In the DHCP settings

    Deleted all the client entries from both DNS servers. Added the second DNS to the DHCP Settings

    Changed DHCP to force DNS updates if the client doesnt request them.

    Scavinaged Both DNS's for stale records.

    I will add to the note that the DC has alot of DCOM errors in the Event viewer which i cant get to the bottom of. Error 10016. Could this be to blame?

    Unfortunatly, i cant seem to wake any of the clients remotly for some reason so i dont know if any of this has helped.

    Your thoughts?

    Have you tried remoting clients using the IP address instead of the machine names?

    RAID Arrays do not, as a rule, randomly rebuild themselves. I suggest you dig deeper as there may be a bigger problem about to occur. A faulty disk/RAID array will cause random problems like those described. DNS too can cause issues such as this, but I suspect that you may have a disk(s) that will need swapping out soon and what you are seeing is symtomatic of this. I may be wrong, but that would be my guess. You will have to check your RAID diagnostics for further infomation.

    @bodminman - yes, if i look in the dhcp records for the machines IP your straight in. Go via machine name and something your connected to a totally different machine.

    @Dos_Box - i was way to busy that day and was maybe hoping that would have been why the system was so unresponsive... I recall it having a bad restart that morning due to just every app /servicve/ you name it just not responding.. it was probably just resyncing the drives after a abrupt restart. Drives since then have checked All Ok

    Certainly sounds like dns to me.

    What about date/time settings across the site. How are these set?

    @bodminman

    Was just reading up on these two.

    seems to be conflicting infomation ref the DHCP. Do you thing i should create a Domain Admin account just for this and enter the credentials?

    Is there a time disparity between clients and the DC?

    Have a look at the disk access on your server using performance monitoring tools, I really think you need to be 100% that the array rebuilding isn't causing this, you've said that the processor and ram were normal which usually means your dog slow server has disk access problems which are likely caused by the rebuilding, you might find that the failing disk comes back to life for periods which would cause the sort of intermittent problems your seeing, espically on a dc.

    Which is what I said earlier. I suspect he's trying to fix the symptoms, not the cause.

    There was a Windows Update a couple of weeks ago which made the "applying Computer Settings" prompt seem to take a bit longer than normal, but a couple of reboots later it was fine. I think it was configuring the latest .NET.

    Im led to believe that this could be due to DNS Problems. (which have been about for a while.)
    I have demoted the second DC and removed DNS off of that a couple of days ago, so were are just down to this one.
    The second DNS is still showing in the DNS records as a name server. should i remove this or will ir go by itsself. I know NOTHING anoud DNS, its just self learning black magic to me. So where do you start about trouble shooting it? is there a way to just factory fresh it?
