Hi there, I have my mobile (WM5) activesync set up to synchronize with my Exchange Server 2003. As for the settings for the server address (on my mobile device) I use my server FQDN (e.g. myserver.com) and anytime I am within my wireless network I got the mobile connecting via wireless and synchronizing with my Exchange server. If I am not within my wireless network range I am syncing either via GPRS or different wireless. I had to change the router for my local network (from Netgear DG834G to D-Link DSL-G624T) and now I cannot sync via my local wireless. My mobile device connects to my wireless without any problems. I can browse the Internet, etc, but cannot sync. Only when I use my Exchange server's local IP address as the server address setting on my mobile device, it connects and syncs, otherwise I am getting 0x80072efd "Waiting for network" error. It seems that it must have something to do with the new router DNS settings (or cached mobile settings?), but I would really appreciate if someone could guide me some clues how to tackle this problem. Many thanks, Jay
