Change schema master role

I had a problem to change schema master role DC with w2k3 Enterprise Edition through GUI interface (MMC). So it should be done through (somebody has same problem with server 2008) :

"There are a few ways to achieve this - I would use the NTDSUTIL tool.

• From the 2008 DC, run ntdsutil from a command prompt
• type ROLES and then enter
• type CO and then enter
• type CO TO SERVER and then enter
• type Q and then enter
• type TRANS SC MA and then enter
• you will be prompted with a GUI box whether you want to transfer the schema FSMO to that DC, click Yes
• Q and then enter
• Q and then enter"
