Server/domain help

I have seen on servers, where you can set up a domain, and other PCs can connect to that domain and share programs, printers, etc.

My goal is to set up a server and share Quickbooks on all the PCs, so everytime invoices are updated, they are updated on the server so all PCs stay current.

My question is, how do you set up a domain!!!!?
Do I need Win2003 server, or Win2000 server? Can it be setup using win2000 Pro, or Win XP Pro?

 

You don't need a domain or even a server to network QuickBooks, a workgroup setup with the business files on the server will work just fine.

 

i see. thanks for the reply. but just out of curiosity, do i need a server O.S. (win2000 server or win2003 server) to set up a domain? like if i wanted to share other programs like MS Office. Do i need to install on all the computers, or can i run them from the server?
