  • KB article now available for 20+ processors issue

    Posted on October 25th, 2010 By Andreas Stenhall + No comments

    Not long ago I posted about the interesting issue of Windows Deployment Server services not starting when having more than 20 logical processors on the machine. Now Microsoft have published the KB article for the problem regarding Windows Deployment Server service but  it also seems to affect ntdsutil as well. Again, running a deployment server or a domain controller on a server which has more than 20 logical processors is not very likely but still it’s kind of an interesting issue.

  • A bug in the DNS service in Windows Server 2008

    Posted on February 16th, 2009 By Andreas Stenhall + 2 comments

    I’ve seen quite an interesting behaviour of the DNS service in Windows Server 2008 for a long time without even thinking about the DNS service having a bug. Apparently there has been a fix for this issue out since summer time but it was not until Microsoft blogged about the bug a few days ago that it got my attention.

    The problem is with secondary DNS zones that suddenly loses all (or many) records of the zone, which is not a very good thing I can tell you.

    After reading through the description of the bug a couple of times I just sat there with my mouth open. This is exactly what I have been experiencing for some time now. So what is the moral of the story? Always check if it is bug!

  • Deployment bug found in Vista RTM

    Posted on December 16th, 2007 By Andreas Stenhall + No comments

    Long time no see! I have lots of things to blog about, I just haven’t had the time to do so lately. Last week though I learnt  about a tricky NetBIOS computer naming bug when deploying Vista using Windows Deployment Services (WDS). As you might know  the NetBIOS computer names cannot be longer than 15 characters and when you in Windows Vista (and all previously released Windows versions as well) change the computer name to a name with more than 15 characters you will get a warning message
    that will look something like the screenshot attached to this post.

    Computer name change

    When using Windows Deployment Services with the new option “Name and approve” the client before pushing out the image to the client, you can as you might have figured name the computer object in Active Directory and then fully automate the  installation process. In the unattended answer file in the computer name section for deploying Vista we have entered %MACHINENAME% to make sure that the computer name is not randomly generated with a name like LH-XY45YHGKL and to make sure
    that we will not get any questions to answer when deploying automatically.

    We have a computer naming standard which obviously sometimes makes the computer name more than 15 characters. The bug is when you name a computer longer than 15 characters during Name and approve in the WDS. Then the unattended installation will fail at the specialize pass, without any particular error message, probably because it wants to show the same error message dialogue as when we are in the GUI version of Vista.
