Hi dears, In our company setup we have installed MS-ISA 2000 with DSL line in Head office. Our head office is connected with all branches with 64K DXX links. Now i want to install MS-ISA 2000 in all branch locations so that all ISA boxes hits the Head office ISA server for connecting to internet, so that they will create their own cache at each branch for fast access. Please guide me through this setup?
