DNS Help needed

I have a Windows 2000 AD domain with DNS installed on my Global Catalog server. My DNS root namespace is mycompany.com. I have added another domain to my forest. It is not a child domain of the existing domain. It is its own domain with its own DNS namespace but again within the same forest. For example the name is myothercompany.com. During the DCPromo of myothercompany.com I installed DNS. It joined the forest with no problem whatsoever. But when I look at the Forward Lookup Zone on myothercompany.com there are no subfolders created. I don’t have the folders “_msdcs, _sites,_tcp, _udp. On my first DNS server I am getting NTDS KCC errors stating that it can’t replicate the link with my new server because of a DNS lookup failure. Any assistance on this would be greatly appreciated. Thanks in advance.
