I currently have an office running on ISP "A". In this LAN, I have the Business Server which they all can access and share. We extended our office and have a different building that will be using ISP "B" (different). What would be the different ways to integrate both offices so they can both use and access the Business server while maintaining their respective speeds (ISP B is faster thatn ISP A)
Some Details: Business Server has 1 NIC card and Offices are close enough were a cable can be run in between them.
