Time Zone Update for Outlook(Exchange) and server 2003

Question

Hi,

I would like to get the patch to update the time zone for all the servers of my company.

We are using server 2003 standard and the daylight saving is schedule this Sunday at 2 a.m.

I have to update all the servers as well as the exchange server with Outlook calenders.

Our current time zone is GMT +10:00,  Australia Eastern Standard time. We are based in Melbourne.

Please help me.

Cheers,
AL
