In a simple Adagio installation (OE and IC) with 3 users, we are running into some locking issues.

- When user 1 logs in first, user 2 can login but user 3 can't.

- When user 2 logs in first, user 1 can login but user 3 can't.

- When user 3 logs in first, user 1 and user 2 can login.

This was installed by their IT guy who is good at following instructions, but it appears he veered off somewhere. Based upon those symptoms, can anyone provide any potential solutions.

BTW, they are using VISTA
