During this Support WebCast, you will learn about the various ways that you can deploy Microsoft Office XP Service Pack 2 (SP2) in an enterprise computing environment. You will find out how to use Ohotfix.exe to chain client-side patch deployment and administrative patching. Because SP2 is a new baseline for Office XP, you will also hear how this will affect the rollout of Office XP in an environment where previous versions of Office XP have been deployed. You will also learn how to provide additional failover resiliency for client-side patches and how to use some of the new tools that are available on the Office Resource Kit site to manage patches in your environment.
