I want to decommission my SBS 2003 and have a standalone Win 2003 DC and Exchange server. I followed both parts of this guide:
So all operation master roles, GC, FSMO are transferred and my Exchange is running fine. Now I need to remove SBS2003 off the DC list and it won't let me. I tried running DCPROMO but it complains that it cannot contact any other DCs. If I specify it's the last DC in the domain, it won't do it either.
Back on the new DC, I go into AD Users and Computers, right click on SBS2003 and try Delete. I tried even the "This domain controllers is permanently offline and can no longer be demoted using Active Directory Installation Wizard (DCPROMO)" option, but I get an ACCESS IS DENIED.
Tried deleting it using NTDSUTIL and ADSIEDIT, ACCESS IS DENIED. What the flop is going on?! Please help!
