I use Exchange 2003 and AD in a same server.There is enough hardware for the server.
The problem is like these:When I go to the Exchange OWA page either from inside or outside of the network, the page loads fast.
But after I enter my username and password, I must wait about 120 seconds to see the OWA web page.
After that the OWA is fast in what ever you do.
If I log out and then back in it is fast, I can immediately back into the inbox & messages.
Can someone help me? How can I fix this problem?Thank you!
