Here is my dilemma. I presently have six computers on a domain, a server and five clients. This group runs our practice management software (the PM domain). I then have about 14 computers on a P2P network, of which one of them is our AC server. All of the computers have AC installed on them (including the domain computers) and talk to each other through a network switch. I had AC and STI (our practice management software vender) get together and write a bridge to transmit demographic data from our practice management software to AC. I was informed that for this bridge to function optimally, the AC server should be joined to the PM domain. The question is, can the AC server become a member of the PM domain and still serve as the server for the P2P computers? Would it be easier to just close the practice and move to a warmer climate?
