S620 suddenly won't sync using WMDC 6.1

[JayRayMee.NL]

Hi people,

My HTC S620 suddenly stopped synchronising with my Windows Vista notebook using the Windows Mobile Device Center 6.1.

I also have a HTC X7500 which I also sync with the same PC (along with some other Windows Mobile devices now and then) without any problems.

But.... today the S620 suddenly stopped syncing. When I connect the device to the notebook there is this Vista connection sound (so the device is recognized) and the WMDC also recognizes the phone as a connected Smartphone including my device name. It notices the date and time of the last successful sync, which is correct.

The thing is that it doesn't do anything else from that point. It should start syncing by itself, but it doesn't.
The WMDC mentions 1 error: the syncing can not be completed. Cause: error. Please see http://go.microsoft.com/fwlink/?LinkId=72544. - saying nothing at all.

Removing the partnerships on both the PC and S620, rebooting computer and S620, it doesn't matter, the sync just won't start anymore.

When I connect my X7500 again, there's no problem at all...... the syncing starts like it should, but just not with the S620 anymore.

So where is the catch and how to solve it?
Thank you for the help!!

Hmmm strange, but here's an update:

When I turn off the Windows Firewall, the S620 suddenly starts syncing.
How can this suddenly be a Firewall issue?

Everything regarding "Windows Mobile" is checked in the list of allowed ports/programs and the S620 (and X7500) WERE syncing before, with the firewall being activated.

Any suggestions?

You'll have to delete the current partnership and establish a new one to get WMDC 6.1 to sync with a device that was sync'd with the older (original) version of WMDC.

Unfortunately that isn't the case. The S620 DID sync until yesterday. Before that everything was perfectly fine, with the same WMDC 6.1.

Go in Settings->Connections->More...->USB to PC

and untick use advanced networking.

I had the exact same problem, when I installed 6.1 I can't get any devices to sync when advanced is ticked. And even going back to 6.0 doesn't fix it!

That last hint worked for me...thanks.
