    Hi Awinish,
    Can you please help me with the install mode on windows server. Also, please clear the doubt regarding :-
    1) While installing a program on windows server 2003 or 2008,do we need to do it in the install mode ? Is it mandatory ?


    •   Awinish Says:

      Install mode was in NT,windows 2000 etc & in older dell hardware which can be turned off, using local admin group membership ID you can install/run any program in windows 2003 or 2008/R2.
      In windows 2008 R2 there is UAC(User access control) which requires any software/application to be installed using runas administrator, reason prevent non admin user to install software. Even though you are member of administrators group, if UAC is enabled, you are required to use runas administrator for installing or launching application, administrator account too is controlled via UAC.

        Thank you Awinish for the reply. So, if i understand you correctly, there is no need to go to command prompt and execute the change user /install command to switch to install mode on windows 2k8 R2/windows 7 or windows 2k3 server? I can directly install it using run as admin (on windows server 2k8/windows7) and in windows 2k3, just execute the .exe file? Can you please clarify me on this matter. i appreciate your help.


  2.   Awinish Says:

    Yes, you don’t required to go to cmd to change the mode, speaking truly, i haven’t used till now this install mode, so you require a account which is member of local admin group thats it & in windows 2008 you need to use runas administrator option(UAC can be disabled compromising with risk, but its not recommended) to instll software.

    What is the use of authorive and non authoritive restore mode? when to use this mode and how to do?


  6.   Awinish Says:

    I would presume, you are talking about AD Authoritative/Non- Authoritative restore. Authoritative restore of AD is pushing the changes to other DC’s in the forest where as Non-Authoritative restore means pulling the changes from other DC’s to restored DC.

    Consider, you deleted a object by mistake & you want to restore it back, since object is assigned with USN no, on any modification USN no is updated, so object which was deleted has its new USN no & marked for deletion in TSL.

    Since all the DC’s in the domain has been updated with New USN no on deletion, if you restore the object from backup which is prior to deletion have old USN no than deletion USN no. Once you restore the object it is non-authoritative, but since USN of deleted object is higher, once you restore & reboot, it will check on other DC’s in the forest & will find its USN is older & they have info this object is deleted, so they will delete it back.
    In order to preserver the object we have to mark the object authoritative after restoring the object using backup in DSRM mode.

    I am really in trouble with my Exchange server. I have an IBM 3650 M3 server with Windows Server 2008 R2 x64. I have installed

    active directory and microsoft exchange server 2010 on it. I have taken a full system backup using Windows server backup. Now the

    problem is I cannot restore the same environment on a different hardware. I have done authoritative system restore on a HP Pavilion

    but after restarting it is giving blue screen error. No way I can get back to the system.

    If full system restore is not possible on a different hardware then please help to accomplish at least two things..

    1. I want all the active directory users with all OUs to be restored on a differnt system with same or different domain name.
    2. Restore the mail boxes on the exchange server and sychronize between AD and the respective mailboxes.

    By doing this I can bring back my exchange server. Can anyone help me?

    Thanks and regards,

      System state backup on different hardware is neither recommended nor supported.Even though you can install on similar hardware but in most of the scenarios it doesn’t work due to difference in driver level let it be graphics,NiC or any other.
      Running Exchange on DC is a bad practice, due to various implications like performance, security,not able to contact any other GC apart from the DC it is being installed.

      Don’t try to restore something like this means system state backup of one dc to another as it doesn’t work.

    Dear Mr.Awinish,

    I want to put two DC in different locations. I need to use DC name as my company name (Eg: not ‘abc.local’. What i will do next? Domain name reg is possible freely and it secured?


    •   Awinish Says:

      Domain name registration on internet is not free, but you can use use any domain name hosting internal AD. Domain registration is required when you want to publish your domain on internet. You can have any name as long as its not conflicting with already existing domain in your network.
