I've got a problem with OWA, and I'm pretty much at the end of my rope with this. OWA authenticates perfectly on the internal network. No problems at all. On the outside, you have to log in two or three times before it "sticks" at which point it won't ask you to authenticate again for hours.
The problem cropped up after an admin left and we were forced to change a bunch of passwords, so it's almost certainly a password/directory ownership issue somewhere. However, I've gone over the configuration and I can't find anything that's not running with a password unique to the local machine.
The setup is Exchange 2003, running behind an Apache proxy. Since the problem is external only, I've gone over the proxy extensively, and I can't find any problems. The whole setup has been running fine for ~4 years, so again, it's probably tied to the password change (which shouldn't have effected the proxy in any way).
I'm sure it's some stupid configuration setting that I'm missing, but I can't find it for the life of me. Anyone have any ideas?

I'm pretty sure this isn't the problem. Nothing has changed on the proxy, and this configuration has worked for years.
