Sysprep not changing my SID

Posted on 2009-02-24
Last Modified: 2012-06-21
I have two webservers. They had the same SID (verified using NEWSID to check it). So I ran sysprep on one. When I finished reconfiguring it, I checked the SID and sure enough it was the same SID as it was before I ran sysprep.

Any ideas on how to fix this? NewSID let's me change it, but Microsoft doesn't support systems changed via NewSID.

    What is your servers OS? You should use SYSPREP designed specifically for the target OS.

    We are using windows server 2008 standard edition, 64 bit.

    If you refers to sysinternals' NEWSID then pay attention to OSes it works on - WinXP and Windows 2003. There is nothing that confirms you could use it on Windows 2008.

    Also, the options for Sysprep have changed from those available in  Windows Server 2003 and Windows XP. Read carefully the sysprep technical reference:  You probably need to use /generalize switch if you want a new SID.

    Also check if your sysprep.inf uses the correct settings as there are a lot of changes (

    Hope it will help.

    I was probably not using the command line /generalize option. I ran newsid and it worked but now i'll probably do it again with sysprep just to be compliant. Thanks!
