ISA 2000 vs. 2003

[MISMCSEJERSEY]

I am upgrading Microsoft Proxy to ISA. I have AD 2000 and want to keep AD 2000 and not upgrade to AD 2003. Should I add ISA 2000 or 2003? I am also adding an Exchange should I add 2000 or 2003? I have prior experience with ISA and Exchange 2000 only.

I mean ISA 2000 vs. 2004 Sorry.

If I go ISA 2004 with Exchange 2003(with Server 2003), should I buy Server 2003 for the ISA 2004 (I have Server 2000 with Proxy and plenty of resources). I would prefer to stay Server 2000 for ISA 2004 to avoid the cost. Remember I have AD 2000 in place.

My understanding is that ISA 2004 requires Windows 2003 and if integrated with Active Directory, the AD 2003. That is what has stopped us from upgrading at this time.

If you upgrade to Windows 2003, you also have to upgrade all of your CAL's. The company I work for was looking to do Exchange 2003 on Windows 2003, unfortunatly, the cost for upgrading the CAL's for both Windows and Outlook (for OWA), was about $100,000. Way out of the range for our planned conversion from NT4 and Exchange 5.5 to Windows 2000 and Exchange 2000/2003.

From what I recall, you dont *need* to use the active directory integration unless you have multiple ISA servers running together and want to control them through AD.

Heck, we are running ISA 2004 and dont even have it connected to AD or the Domain, much less using the integrated features - dont really need to have a DMZ server contacting our DC, so we didnt bother.

If you dont need to control ISA through AD, then go for 2004, much nicer to operate IMO
