I have been following the TechNet article http://technet.microsoft.com/en-us/library/bb691354(printer).aspx
Are the hotfixes a requirement before installing Exchange 2010? The reason I ask is I have been having difficulty finding two hotfix updates under Windows Server 2008 R2 section. The hotfix for the WCF Services.... KB982867. I couldn't find the update to download for R2.
The update for KB983440 for ASP.NET 2.0 hotfix rollup package it seems to require contacting Microsoft. All this is leading me to wonder are these hotfixes even necessary...?
