SID creation

[Hondy]

Hi

I'm making an installation image using sysprep which involves setting the server up how I want then "sysprep /audit /generalize" then shutting the server down and taking an image of the disk.

When it starts back up again, how is the SID generated and why will it be different for each new server?

Thanks

thanks the first 2 links are the same and doesn't tell me what I need unfortunately, 3rd link is for XP and doesn't tell me about SID generation process either.

I suppose what i'm asking, is a new SID created as soon as sysprep has ran, pre-reboot, or is this when it is removed only.

It would make sense to me that you run sysprep and it strips all the config including SID, then when it boots up again it says "hey, I'm a new computer, I'd better generate some SIDs etc" - but I'd like some confirmation as I can't seem to find it anywhere.

Cheers

Oops my bad on the duplicate links. But Yes that is what sysprep does, it removes the SID info then reboots and generates a new SID. Now what keeps sysprep from generating a duplicate SID I am not sure about. But in a nut shell yes when it boots up that is when new SID generation process happens.

sweet, thanks I thought so. Do you know what the SID is based on? That is, what seeds the number generation?

 

[w33mhz]

No, I don't. My best guess would be that the seed is dirived from a few different things like date\time and systemboard GUID. But that is just a guess, I really don't know.

Maybe this has the info you want.
