First of all Bert, congrats on breaking the 10K posting barrier. That's truly amazing. Second, the reason that I do not want to join all of the computers to the domain is because it is "scary". I know nothing about client/server configurations and if I did implement that, I would have to try to learn all that stuff, or hire an IT person. I have nothing against IT people, but right now, I can troubleshoot and fix 99% of the computer problems I encounter during the day. I probably could not do that with an entire office domain structure. I hate relying on others to try to fix important problems quickly. Another issue is our PC domain server. It is running Windows Server 2003, has 4G ram, a 160 GB RAID-1 Drive configuration, and it has hardware dated circa 2008. If the other office computers joined the domain, wouldn't it likely overtax that old server? If everything was on the same domain, could my AC server remain the AC server and the PM server remain the server for the practice management software? Also, wouldn't I have to buy a bunch of client licenses to allow the PM server to connect to all of the clients? Sorry for all of the questions, but this is unchartered territory for me.
