Ok, a rather long title but I didn’t want to go too far on the paraphrase. If you work with SharePoint I’d recommend a look at the latest blog post by Spence over at Groundhog Day: Configuring Back Connection Host Names using Group Policy .
For one thing it is a nice reminder that SharePoint administrators need to understand their infrastructure. Sure we can’t keep all of the detail in our heads, but at least know the roles of the technology and what to use to do what. In this example Group policy is used to implement something on the servers in a farm.
