Recently we switched over from a DSL Internet connection to a T1. As a result we changed our router and public IP address.
Up until the change my 2 mobile users (WM6 on alltel) were getting their push email from exchange no problem. After the change neither can sync any more; they get the '85010014' error code.
-I did change our domain registration to reflect the new IP and from the outside I've verified the name resolves to the new address
-We did open port 443 on the router and I can access our OWA via https
-I also captured network traffic from the SBS server and I can see the phone will start a conversation with the server but after only 5 secs the phone sends a RST,ACK packet.
-We also temporarily opened all ports on the router with no change.
-A quick review of the 3rd party signed security certificate only shows the domain name (no IP numbers)
Does anyone have any ideas of what the problem might be or what specifics logs/settings I could check to find an answer?
