Vista

Install the adminpak.msi like normal, and then register about 20 DLL files manually - you can get the full list here.

You'll want to grab it here. You can think of IE Protected Mode a lot like a chroot.

I finally have a Motorola Q and can use Exchange Push fulltime!

I am running an older build of Vista at home (post-RC1, pre-RC2), but I wanted to sync the PC with the new SmartPhone. If you want ActiveSync support for Vista, you'll want to grab WMDC Beta 3 here.

I've always loved to hate ActiveSync but so far WMDC seems to work out of the box as intended.
