I have 2 users set up on my windows xp pro machine with fast user switching enabled. User A has PDAs that sync with activesync. User B does not. When user a logs in- he can sync no problem. User B logs in with User A's profile still running in the background. After that- Activesync defaults to not allow USB connections- preventing further synchronization until that option is checked off again. Many times- activesync will just disappear all together and come back after both users log off and one logs back in.
Any ideas?
