sysprep and still SID errors

Hi,
I've created a VM in virtualbox, used sysprep, cloned it and still getting SID errors on the VM.
This is the situation:
1. Created a VM
2. Installed Windows Server 2008 R2
3. sysprep
4. Clone
5. Created a DC on one of the VM
6. Created users in de DC
7. Can select the AD user on the other VM (add to group administrator)
8. name and SID shows up (S-1-5-21-...)
9. Error : user already exists when i press ok
So it seems that the sysprep didn't work or whatever. I don't understand.
Run a diagnosis with ntdsutil but the logfile is empty.
Gr,
Hennie

Did sysprep process run during boot while you switched on the cloned VM?
How many cloned VMs you created?
Why are you trying to add local users from other VM to DC VM? What accounts are they?
Built in or manually created?
Also try if possible demote the DC, run NewSID v4.10 utility and re-prmote it.

Hi Hennie,
Could you expand a little from steps 6 through to 9, please? There's not enough detail there to form a clear idea of what's going on.
If you could perhaps provide an example while focusing on one account so that we can follow what's happening with that account from it's creation (during step 6) through to the error (step 9), that would help a lot.
Cheers,

Here are my answers
Did sysprep process run during boot while you switched on the cloned VM?
Nope. first sysprep and then a clone.
How many cloned VMs you created?
1
Why are you trying to add local users from other VM to DC VM? What accounts are they?
No, just users from the DC. Just normal users. nothing special.
Built in or manually created?
I've created them by myself.
Below i explain the steps 6 to 9 in more detail
6. Created users in de DC
On the DC machine i've created users in the"active directory users and computers" .
On the users sibling i've created a couple of users. Myself as a test acount and a couple of
7. Can select the AD user on the other VM (add to group administrator)
On the other VM i can select the user when i add the user at the "computer management" (add to group), the DC is shown and i enter a login and password and i can select the user i want. Great.
8. Name and SID shows up (S-1-5-21-...)
When I add the user from the DC on the other VM ( add to group) a SID is shown. When i look up this number on Microsoft site it says something about cloned user..
9. Error : user already exists when i press ok
This error appears when i press the OK button in the "Add to group" window.
Error appears also when i try to add the other users.
Currently rebuilding another VM for building a SQL Server environment. Hope that the error is gone...
Greetz,
Hennie

With sysprep did you select "Generalize" ? If no then the SID is not changedMCP | MCTS 70-236: Exchange Server 2007, Configuring

Run the SID checker to see if the SIDS are indeed different.:
