misfol,
I found this on another forum, quote: I was having problems sync-ing my
Cingular AT&T 8525 (HTC TyTn/Hermes) to my Vista Ultimate installation at
home. Basically it would connect to the Windows Mobile Device Center (the
Vista replacement for ActiveSync) but if I tried to browse the device's file
system explorer would hang... or take a very long to show the device's file
system, then hang when I clicked around. On occasion it would work, but 9
times out of ten it would not work.
Googleing for the problem brought me to the Windows Mobile Device Center
page where I followed these instructions:
On the device, go to Settings, Connections, and look for "USB to PC" option.
Go into the “USB to PC†option To enable RNDIS USB, check the “Enable
advanced network functionality†checkbox and then, OK.
Note – if it’s already checked, do not uncheck or this workaround will not
work for you.
Warm boot the device (push and hold the power button, hit the reset button,
or pull the battery).
Power the device back on.
Once the device is booted up, dock and try again.
Note – RNDIS does have a bit more wait time when connecting. Please be
patient for the device to connect.
If after you do the workaround and you cannot connect at all, then simply
switch back to Serial USB to sync.
Now all is well on Vista back at home and I've confirmed that everything is
still cool at work on XP with ActiveSync. Sweet!

I don't know whether this, or something similar, will work for you, but it
worked for that person.
