What ports need to be opened between your OWA server and your Exchange server to allow MAPI communication between? You almost no longer have a DMZ really.
443 through to your exchange server internal to your network properly secured is harmless. -----Original Message----- From: Tom.Gray [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 09, 2002 12:18 PM To: MS-Exchange Admin Issues Subject: RE: OWA on the same box Might also want to consider security issues. OWA on a separate box on your DMZ instead of opening up port 80 (or 443) on your exchange box to the entire world.......

IIS can run away with the processor hitting 99% of the processor time, and slowing other exchange functions to a crawl. MS has some hotfixes for this problem but they don't seem to work in my environment. Stick OWA on another box if you have one handy, in the long run you will be much happier... -----Original Message----- From: Matthew Carpenter [mailto:[EMAIL PROTECTED]] Sent: Monday, July 08, 2002 2:42 PM To: MS-Exchange Admin Issues Subject: OWA on the same box I heard someone tell me that it is a big no no to run OWA on the same machine as Exchange. Is that true, or an opinion?
