Hi.

I use a PC as testing platform for my developing. This PC has two different
windows instalations (Win2k and WinXP - I can choose which one to boot from
Windows boot menu - I played with boot.ini ;) ).

I want to use the same name for both OSs (only one runs at a given time) and
I also want that those OSs are part of NT domain (I'm using NT 4 PDC). As I
understand the PDC distinguish those PCs from their unique SID.

The question:
Is there a way to 'duplicate' (copy) the SID from one instalation to another
so that the two OSs will have the same name and will be part of the domain
(the trust relationship between PDC and each of OSs will work) - how to do
this?

Regards,
Dezo
 
Duplicate SIDS is not the issue. It is a common misconception
that duplicate SIDS will cause a problem but that is not the case.
Duplicate SIDS are a security risk e.g., users on machines with
the same SIDS will have access to all local profiles on all cloned
machines. The problem is the hidden machine account password
which will be different for each OS. When a machine joins the
domain there is a secure channel created along with a secure channel
password kept by the domain and the domain member. The hidden
machine account password will likely be different for each OS.

If you are not really worried about security you can disable the
hidden machine account password:
