Thanks for the information and the support guys! When I first configured the system I used MS Knowledge Base articles and Tom's book and felt like I kind of knew what I was doing. (thanks for your message Tom!) This IT firm that is advising us were themselves still on NT and Proxy server when they were first hired! But they are quite cheap which suits Opera North who after all are paying a cellist peanuts to look after their firewall (and active directory and DNS,DHCP and terminal services and Exchange and SQL and sometimes SMS when I get a chance - and by the way I also design and update the website www.operanorth.co.uk ) You will understand that the value of the experience and advice of this list is enormous to someone like me! I would be grateful for more support on this topic. If it is actually possible to move OWA to the ISA box what has to be done? (Just so I understand a wee bit more) The more information I have the easier it will be for me to persuade my colleagues that we don't need this sort of advice. None of my colleagues have any real understanding of the issues involved! many thanks Andy Fairley Opera North Leeds England ----- Original Message ----- From: andy fairley To: [ISAserver.org Discussion List] Sent: Saturday, January 25, 2003 9:56 AM Subject: [isalist] OWA on the ISA server http://www.ISAserver.org Dear Exchange list and ISAlist, I have a working setup with ISA on one server and Exchange on another. Only the ISA server has a public IP address. OWA is working via SSL on the IIS services on the Exchange box, with HTTPS requests being directed to it by ISA. This was setup by myself and has worked well for a year. We have just had a consultant suggest that it would be much better if the ISA box did the IIS work for OWA, ie:- that the IIS services on the ISA box dished up the pages for OWA. Is this possible? It would mean starting the IIS services on the ISA box for a start, and I don't think it would be able to use the default ports. What are you feelings about this? I don't like to change a working setup but want the advice of the experts. many thanks Andy Fairley Opera North Leeds UK ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: andy@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
