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.
When you say outside the network do you mean across the Internet or just from the outside of the pix.
Firstly check the speed/duplex of your pix interfaces and the switch ports they are connected into.
Secondly, if you could temporarily allow ip from your source address outside the pix to the SBS and see if that makes a difference. If it does it may be that you need to open additional ports for OWA to work more smoothly.
