iPhone, Exchange 2003, OWA, ISA 2006

I just got done setting up OWA with ISA 2006 for iPhone test users. One thing that I ran into, which I have seen in the past, is an issue when you have an ISA server with only one leg, purely in the DMZ.

With OWA if you don't want users to have to type in /Exchange when connecting to the Exchange server you have to basically create a redirect rule that comes into effect when a user just types in the root of the OWA server. That rule then forwards them to /Exchange. Simple, but a PIA if you are trying to figure it out.

Here is how to do it: http://www.messagingtalk.org/exchange-2007-owa-url-redirection-using-isa-2006

vsphere, TPS, high memory utilization on Nehalem processors

After upgrading from ESX 3.5 to vsphere all of VMs were throwing memory alerts. I found this article

Basically with MMU and large page sizes enabled, TPS doesnt work so well because of the larger page size. For now I disabled the alerts, but there is also the option of disabling large page sizes.

vsphere 4, paravirtual SCSI

From the Admin Guide:

VMware recommends that you create a primary adapter (LSI Logic by default) for use with a disk that will host the system software (boot
disk) and a separate PVSCSI adapter for the disk that will store user data, such as a database.

ESX using NTP has Wrong Time zone on command line

The ESX servers at my customers site all use NTP. This is working great. All the VMs have the correct time using VMware tools, when I check the time under configuration, it shows the correct time, etc. However, when I log into the ESX server itself via SSH it has the wrong time when I run the date command.

This is because there is an incorrect time zone set. This is easy to fix and shouldnt affect your NTP settings.
