Hi About the part where you talk about that comcast is blokking port 443. To my knowledge, when you connect to port 80 to visit a website, your own port nr is NOT 80, but something above 1024. When doing OWA, traffic would look like this: Home port 1099 -----------> request to OWA ------> port 80 OWA port 80 -----------> reply to Home -------> port 1099 I don't think SSL is different in this. For each new SSL connection it will use a new portnr. Otherwise it would be impossible to visit more then one SSL site at the same time. So COMCAST blocking 443, is not the issue I think. Maybe for incomming to COMCAST they block 443, but that is not used in your connection. And if they were blocking 443, there was no connection at all, also not after 1minute wait.

Http://exchsrv2.cs.washington.edu = instant https://exchsrv2.cs.washington.edu/exchange = delay. If it was a DNS issue, it would be slow for both. Even after you connect, and get a DNS cache, it is still slow. Plus, I added an entry directly to my HOST file. 3rd, I have done a netmon capture, and you can see where the delays occur, and it's not the initial portion of the conversation I take ISP out of the picture by doing it at work, asking co workers with DSL to try. I have comcast cable at home, and so do about 20% of the other users on our network. All comcast users report problems, everyone else works fine. I did do a network monitor capture, I just took a deeper look and it appears there is some connection trying to happen to destination port 443, which I know COMCAST is blocking, so the problem is related to that I imagine. I have 2 exchange servers, one is win2k & echc2k the other is win2k3 & ech2k3. Some users on each (planning to move all users to new one, once I solve this problem). Connecting to the older exchsrv works fine, even with the SSL. Connecting to the new one has delays. Is it safe to assume I have something misconfigured, that is telling OWA to authenticate via port 443, where as the older one is not? I will look into it.
