After I installed Exchange 2007 and configure owa, everythings works greate. suddenly OWA form based authentication stops working. However, i can login using windows base authentication. Can someone direct me how to solve? without uninstalling exchange is there any way to remove and reinstall OWA part only? Thanks in advace.

Can you offer some detail on what specifically isn't working? IS FBA not functioning and Windows Authentication is being presented, or are you toggling the setting to test each?Jeff Schertz, PointBridge | MVP | MCITP: Enterprise Messaging | MCTS: OCS

Jeff Schertz, PointBridge | MVP | MCITP: Enterprise Messaging | MCTS: OCS Hi Jeff,Thank you for the reply. Rregular login is working ok, but as soon as i change to form based and restart iis (iisreser/noforce) i get an error message "440 Login Timeout".
