I would like to set up a small business network that has at present only 3 computers. At present there are only 2 requirements, first all must have internet access, and second I want to run an accounting program ( I have already purchased a multi- computer software package) were all three computers can share all the same information. Could someone point me in the right direction? I need type of hardware needed, any additional software, and any other information you think I might need. Thank you!
