I was having some issues getting the Windows Mobile Device Center to connect to my Mobile Device. I checked around the forum and could not find much on the topic. In order to get this to work you need to do the following:
Control Panel
Windows Firewall
Advanced Settings
Inbound Rules
Create a new "Inbound Rule" and name it Windows Mobile Device Center
Click on the "Protocols and Ports" tab
Protocol Type - TCP
Local Port - Specific Ports, 990, 999, 5678, 5679, 5721, 26675
Remote port - All Ports
LEAVE ALL OTHER OPTIONS AT THEIR DEFAULT VALUE
Click Apply
Click OK
Disconnect and Reconnect Mobile Device
Create Partnership etc....
