I had a similar problem. The trick is to initiate the pairing from activesync on the phone. On the phone delete the pairing to the PC. Delete the port on the PC , disable the serial port service, and then re-enable it. In activesync on the PC, disable serial-port connections, make sure you go back to the main activesync app (close all the settings dialog boxes). Now re-enable serial-port connections in activesync on the PC. All this should get active sync and your PC's bluetooth back to before you added the service.

Now on your phone, go to activesync and try to connect via bluetooth. It will say that it can't find a partersship and ask you if you want to create one. say yes and it should try to pair and then connect to activesync on the PC.
