Trying to add 3 computers to existing network server running Server 2003. These are in a separate but next door office. The two offices have same phone and internet connection. We are using a Sharp MX-M350N MFP; these 3 computers need to be able to access the copier for printing and faxing. There is a firewall that the other office recently split due to new law regarding protection of personal information. When the firewall was split, the dsl was also split. This is a wired network. These 3 computers are running W7, the existing ones on the network are running xp pro. These 3 computer only need access to use the print & fax functions of the copier. I don't know much about it but was wondering if a VPN might work.
