IPhone Active Sync will not work on Internal Wifi network
Posted on 2009-05-06
I have an iphone that works wonderfully when it is connected to the 3G network or on my home network. However, when I bring the iphone into the office and connect to the office wireless, my phone stops syncing my Exchange e-mail. We are using the follow:
Exchange 2003 on an Server 2003 box
NO SSL enable
OWA is enabled
imap is enabled
I believe the problem is with DNS resolving the server.domain.com when inside the office but I can not seem to find the resolution.
I put a wireless router on the outside of the firewall, that did not work, I created a new DNS record to point to the exchange server, that did not work.
Any help would be greatly appreciated.
