How to change SID?

[fhpuqrgrpgvirzhpujbj]

I need to change my account's SID to one from a previous install, but all the tools I have found only change machine SID. How can I change my account's SID?

why would you need to do this? Can you give more details -- is this a machine user account, or an account on a domain?

Some more details of what happened and what is not working now would be very helpful.

It's a local user account, and I need to change it because my company wants it to have the same SID the user account had from the previous installation.

Sysinternals "NewSid" could probably do it.

That only changes machine SID, I need to change user SID.

Makes no sense really -- but to change a sid of an account, you would have to change the computer sid the account resides on.. A local account with a sid from an old machine would not be viable on machine with different sid

example

PsGetSid v1.43 - Translates SIDs to names and vice versa

SID for machine\test1:

S-1-5-21-1214440339-630328440-725345543-1013

SID for machine\test2:

S-1-5-21-1214440339-630328440-725345543-1014

the "21-1214440339-630328440-725345543" is the machines sid, the user RID is the 1013 and 1014

So you would have to change the SID of the computer, and then you could change the RID of of the account to match the old one.. MS pulled newsid a while back - since they stated its not really needed.

The Machine SID Duplication Myth

You can still find newsid for download - just not on the MS site.

As to changing the RID portion -- off the top you could just keep creating accounts until the RID portion matches ;)
