I just upgaded my pdc and bdc to 2000. I had to change the domain name so I used my last nt bdc and promoted then demoted the other two and installed 2000 on the new pdc. The old 2000 dc's now after ad has been set up on the new dc won't install ad. It keeps telling me that "The operation falied because. A suitable domain controller couldn't be found." The other problem i have is that when i go to install the oly domain name it takes is the old netbios domain name no the new fqdn domain name. any ideas?
