To All,I've got my own desktop with Windows XP which i install Exchange Management Console 32 bit only. but then when i go to Windows Updates sites there's an option to update the Exchange Server 2007 SP1 to update Rollup 5. Will it also update the main exchange server on my x64 Windows Server system ?is this update safe to apply from my desktop to update my console only ? I'm just wondering if there's any real issue in deploying this update to the real production server. Because I've had very2 bad experience in updating MS Exchange Server 2007 (from failed Autodiscovery, POP3 and IMAP4.exe crash, etc...)Thanks. /* Support Engineer */

Hi Albert, If you install SP1 UR5 then it doesn't update the server, you need to install SP1 UR5 on server. I'd check for any know issues at MSExchangeTeam blog (link given below) and the KB article mentioned for UR to find outknown issues and how to prevent from it.Update Rollup 5 for Exchange Server 2007 (KB941421) has been releasedhttp://msexchangeteam.com/archive/2007/10/26/447356.aspxAmit Tank || MVP - Exchange || MCITP - Exchange 2007 || http://ExchangeShare.WordPress.com

Amit,thanks for your reply.I'll try to do that next time from CMD, by the way do i have to install .NET Fx 3.5 SP1 update before I'm doing the Rollup update ?" Microsoft .NET Framework 3.5 Family Update for Windows XP x64, and Windows Server 2003 x64"/* Support Engineer */
