Hello all, I am having problems upgrading my NT 4 PDC to Win2K and Active Directory. The upgrade process of the OS works just fine - no problems. When the AD installer runs I am in trouble. Here's what's happening: I have my existing NT domain "domain.com" and that is the one I need to upgrade to AD. The AD Installer gives me the option to a) Create a new domain tree or b) Create a new child domain in an existing domain tree. So, I follow the steps to create a new domain tree but when it comes to the point to type in the Full DNS name for the new domain it does not accept the name - our existing domain name. It tells me the name is already in use on the network and I have to use a name that is not in use. Hey, this is my PDC - of course the domain name is in use - shouldn't AD accept it? In my test network I never had this problem. Can I unplug the network cable just for that step and plug it back in once it verified it is a valid name I can use? What do you guys think? Let me know! Thanks! Christoph ----- To unsubscribe, send a message to win2kforum-request@xxxxxxxxxxxxx and put "unsubscribe" in the subject of the message.
