Having a problem with phones syncing email with Exchange. It was working fine until I tried to add a new domain controller to our network and received an error that DNS was missing the SRV record so active directory could not be installed. Someone on here told me to run netdiag /fix which worked and we added that domain controller. Since that happened phone syncing has stopped. I'm not sure what changed in DNS since I still see the pointer for the server name in forward and reverse zones and its pointed to the correct IP. The web piece of exchange is still working as well as all client email is working. Just to make sure something didn't happen to the router I opened ports 1 thru 65000 and forwarded them all to the exchange server and still emails are not making it to the cell phones. Any ideas on what to try?
