Outlook / Exchange Server connectivity problems. Roo 4/24/2007 10:26:02 PM Long story short, I have about 70 computers here I administrate. We use Outlook 2003 as our email client. 5 of the machine have XP Pro x64. Last week the boys out at corporate migrated to a new email server. The 65 32Bit machines connected to the new Exchange server with NO problems. The x64 machines however, did not. You get the nice message "The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action." The 5 x64 machines ping and resolve to the DNS name with NO problems. I am at a loss... Every little tweak I attempt has been useless. Any input would be greatly appreciated! -Andrew

There are known issues with ISA and x64 clients - usually around RPC filters. You may need an update to ISA or to your Exchange server to match up the RPC behaviour. -- Charlie. http://msmvps.com/xperts64 http://mvp.support.microsoft.com/profile/charlie.russel "Roo" <Roo[ at ]discussions.microsoft.com> wrote in message news:41D077AA-B0E9-4C6B-9BD5-D98BCC3DB214[ at ]microsoft.com...

Re: Outlook / Exchange Server connectivity problems. Roo 4/25/2007 4:56:02 AM ISA is not part of our environment. We use CheckPoint as our firewall / routing. After watching the CheckPoint SmartView Tracker, it looks like the server (destination) end is blocking throughput for whatever reason. Tomorrow will be another day of fun.
