While working with Client you get to work on a lot of changes and a lot of modifications to the default configuration of the farm and it is always difficult to work on these changes manually. Recently I was trying to find a way to modify the webconfig file via some command line utility, then, I came across a very detailed article on the the MS blog Hey, Scripting Blog !, which was exactly fit for my needs so I thought of sharing it with all of you as well. At this link you can find a detailed step by step guide by Josh the MS Premier field Engineer, http://blogs.technet.com/b/heyscriptingguy/archive/2010/09/14/use-powershell-to-script-changes-to-the-sharepoint-web-config-file.aspx A zillion thanks to Mr Josh for publishing this for us....!!!
