I started using Windows Vista last October. Since then, I've tried off and on (unsuccessfully) to connect my MDA phone to Vista's new Mobile Device Center.
I've used the ActiveSync for years without any problem, but the Mobile Device Center just wouldn't connect at all. It's not a big deal for me because I sync directly to my company's Exchange server over the air, so I can get anything to my phone that way.
Still, it was frustrating that I couldn't get this connection to work.
I've Googled for the problem (and I've also Live'd for the Microsoft folks reading this), and there were some others with similar problems, but those were all solved with firewall tweaks. None of that helped me.
Well, yesterday I finally got a successful connection. Here's what I did:
On the MDA, click Start, then Settings. Go to the Connections tab and click USB to PC. Uncheck the "Enable advanced network functionality" check box. (does anybody know what that's for?)
Connect the MDA to your USB port and you should get a connection. However, if you try something like copying files to the MDA, you'll notice that the connection keeps getting lost. Go back into the USB to PC setting screen and recheck the "Enable advanced network functionality" check box. That should cure the connection problems. It seems that one connection needs to be made with the box unchecked, and then it can be checked thereafter.
Hope this helps… Now if they would only release that WM6 update for MDA…
