My home network is comprise of windows 2k machine some linux also. Right now I have a situation that been holding back from learning. My first dc is name NYCDC, the root domain is win2k.local. I have problems with joining the domain using AD with a member server I would like to join the existing domain. I always get an error, "Fail finding a suitable domain controller for the win2k.local". Also the other error is "The specified domain either does not exist or could not be contacted". Tell me what is wrong DNS isn’t going out to any site to gather information what do I need to do to have another server join an existing domain as a domain controller, an additional domain controller. I’m I missing some thing in DNS or what? Any other machine can join the domain (Workstations) it fine. Remember I want this machine be join under the root, not a child! Please help, tell me what I’m not doing, or what I’m doing wrong.
