We currently run a network with 4 pc's in our office and want to add a 5th. The purpose of the network is to allow us to run the Act CRM software program as local rather than cloud based. This requires that one of the pc's performs the role of parent (or server) to the other pc's in the office. It is essentially the software and the links that you will be required to set up and get working correctly on the new pc. You can log on using team viewer to do this if required. The parent and 3 sibling pc's are already operating correctly, the additional pc is to be a sibling as well.
