In my office network total we have 80 systems combination of windows 2000 Professional and windows XP and One Active domain controller of Windows 2003 Ent and Additional domain controller of Windows 2003 Ent.
Now my question is can I install ISA 2004 Enterprise server on Additional domain controller to provide internet to the active directory users with firewall policies.
If yes please provide the step by step guide
If no what is the best solution to provide internet to my active directory users with affect of internet policies.
Thanks in advance
