I just installed Small Business Server 2003 and am using it for Email (exchange) services. OWA works great inside the network but it is so slow outside the network that I know something is wrong. How can I identify if it is something in the PIX 501 firewall causing the issue? I can't just take the PIX off the T1 since it is doing Network Address Translation. Please give me ideas, I'm working this weekend and desparate to solve the problem.
