Options for metadata cleanup

Hello,

I have a problematic Windows 2008 DC that I need eliminate from my AD. Even Dcpromo /forceremoval does not work on that DC, so I need to do a metadata cleanup and decommission the server.

The following KB article recommends the use of NTDSUTIL and combination of other tools:

At the same time, the following article provides a GUI only alternative to NTDSUTIL tool:

I like the GUI only approach however, I wonder if GUI approach is as safe and efficient as NTDSUTIL command line?

Thank you,
