Can't connect Windows Mobile 6.1 to Windows Mobile Center

I have a Windows Mobile 6.1 device that I need to connect to Windows Mobile Center via Blutooth.

Note: The same steps Works with a Windows Mobile 5.1 device in the same computer, and I tested with two different computers.

1. I can pair the PC and the PDA without problem.
2. In the PC I run Windows Mobile Center.
3. In the PDA I run ActiveSync and select "Connect via Bluetooth".
4. The PDA open a window with the text "Openning port...".
5. The text changes to "User authenticated".
6. The window closes, and a full screen message with title "Synchronization Error" and text "This device is not allowed to connect to desktop computer" appears.

The PDA is a new and clean device. The computer isn't connected to Active Directory Domain. It has Windows 7 (the two computers tested)

I thing this is a security configuration, but I can't disable or grant access. The pair Works without any error, and I can see the pair settings on the PC and on the PDA.

Thanks for your help!

In the end the problem was that the device was locked for security. The manufacturer sent me a cab to disable security, which in this case only annoyed.

If someone has the same problem, send me an email to duefectu(a)sd-a.com and I will forward the file.

Thanks for your time!
