• In Windows Server 2003 the tool “newsid” is working fine
• For example working with Hyper-V and export/import virtual machines…(clone VMs so to speak )
• In Windows Server 2008 (R2) the tool “newsid” kills your Operating-System easily

• So what’ s the solution for that issue and how can we change the SID another way…!?

Let’ s try S Y S P R E P !

1. First we take a look at the current SID with “psgetSID”. You can see the name of the machine and the current computer-SID
2. Now press “Windows button + R” (run)
3. Type in “%windir%\system32\sysprep\sysprep.exe“
4. Choose Enter System Out-of-Box Experience (OOBE) and Generalize (Verallgemeinern)
5. It will take some time for sysprep to finish, so grab a cup of coffee and wait
6. After the reboot the system is going to change some systemproperties until the following screens will appear. Adjust the settings and finish the sysprep…
7. After that we take a look at the SID for a second time…Oh look, there’ s another one and the computer name has also been changed
