I currently have a SBS 2003 server with 30 user CALs installed along with a Windows 2000 server running TS. My plan is to install a third server, Windows 2003 Standard, that will run ISA Server 2004 or 2006 on it to act as our firewall. The ISA server will be connected directly to the DSL coming in and then control the traffic to the DMZ (where the TS server is) and the LAN.
My question is - Will I need to purchase additional licensing for the Windows 2003 server that has the ISA running on it? Does my SBS 2003 CALs cover those licenses? I have the Microsoft Action Pack so I have 10 licenses for the Win2k3 server already.
Please let me know if you need any more information than what I am giving. Thanks.
