I just took over a small network that is running nt4 with exchange . who ever setup this domain never setup DNS all DNS servers are setup to public servers network running WINS. Ok so I am in the process of upgrading this domain to windows 2003 SBS. Ok so far the windows 2003 SBS box is installed (SBS PORTION HAS NOT BEEN COMPLETED) the 2003 box has been joiend to the nt4 domain (we will call this a-domain) I can not promote the 2003 box to a PDC since DNS was never setup in a-domain (ive never setup DNS on a nt4 server) so basically i need to know how to get DNS configured on a-domain so i can promate a windows 2003 box to a PDC then i will need to complete the setup so that box because windows 2003 SBS server HELP!!!
