I recently tried to download and install the iSCSI initiator from microsoft.com on a Windows Server 2008 R2 server. I kept getting an error on install saying “Setup could not find the update.inf file needed to update your system.
I found this post: www.fixed4free.com/answers.php?id=217664
which states that you will get that error if you are trying to install it on an unsupported system. Apparently the iSCSI initiator is built in to Vista and Windows 2008 so you don’t need to install it.
Found it under Administrative Tools.
