Q: SBS 2003 w Exchange 2003 SP2, patched with KB 931836 and KB 926666, then rebooted: OWA clients see DST rules in TZ picker in both basic and premier client modes.  I expect them to see new Pacific TZ in picker but they see DST 2006 version, Pacific + Tijuana.  What is wrong?
A: This behavior can occur if the client is not patched.  Parts of the dialog rely on the client's time zone database for information.
