RE: Availability of OWA - is it 24x7?

[ONG Liang Bu (CSC)]

Thanks for the reply.  The load balancing only work on the web server that is at IIS level. But the mailbox still reside on IS, If that IS is doing online defrag at exactly the moment that IIS try to pull data, then what happens?  I will think the online defrag should not affect. If it found out this mailbox is engaged it should ignore and go to next mailbox.  Any other reason, I have a remote backup agent running; if the backup kick in will this affect? -----Original Message----- From: Lathrum Matt-P55173 [mailto:[EMAIL PROTECTED]] Sent: Sunday, May 12, 2002 1:53 PM To: MS-Exchange Admin Issues Subject: RE: Availability of OWA - is it 24x7? For 24x7 availability, you could load balance between two servers and bring them down at different intervals to do maintenance.   -- Matt Lathrum General Dynamics Decision Systems                     When cryptography is outlawed,              bayl bhgynjf jvyy unir cevinpl.   -----Original Message----- From: ONG Liang Bu (CSC) [mailto:[EMAIL PROTECTED]] Sent: Saturday, May 11, 2002 10:45 PM To: MS-Exchange Admin Issues Subject: Availability of OWA - is it 24x7?   Hi,   Some users have been complaining that our OWA is down on certain hours during the night. We have only one OWA server.  At nite when the IS do auto-defrag, read from this list somewhere it is twice a day, will the OWA lost connections?   If there is a downtime, how do I find out the time slots and inform the users?
