SYMPTOMS
If multiple Exchange Server computers service Outlook Web Access (OWA) and one of those servers becomes inaccessible, OWA stops responding (or &quot;hangs&quot;) for the users that are trying to log on to the inaccessible server and also the users that are trying to log on to the other servers until the attempt to log on to the inaccessible server times out.



RESOLUTION
This behavior is by design.



MORE INFORMATION
OWA also stops responding when the Microsoft Windows NT domain is synchronized. During this replication process no OWA users are authenticated, which causes OWA to stop responding.
