Well, your 6700 must be set up OK to sync with desktop. Your laptop is prolly where the problem is. So you have AS set up exactly like the desktop, e.g. allow USB connections? How bout that Trend Micro, did you completely disable? Did you try to uninstall the 6700 drivers from device manager and reinstall? The driver installation may be messed up. If you think this may be the case, follow these steps:
1.Keep your device connected
2.From the desktop, go to Start > Start Search
3.Enter "Device Manager" or "devmgmt.msc" to launch the Device Manager window
4.Look under the "Network adapters" node for "Microsoft Windows Mobile Remote Adapter". If this is not present, skip to step 5. Otherwise, right-click "Microsoft Windows Mobile Remote Adapter" and choose to "Uninstall"
5.Look under the "Mobile Devices" node for "Microsoft USB Sync". If this is not present, skip to step 6. Otherwise, right-click "Microsoft USB Sync" and choose to "Uninstall"
6.Disconnect and reconnect your device. Your device driver will re-install and AS will launch.


On the BT side, did you create an incoming COM port to sync over?
