Log:
1.0 – Original script 11/27/09 based on the work of Anderson Patricio and Bhargav Shukla
1.1 – 04/09/2010 – added help; downloads of update rollups; cleanup of variables; added another option for typical install w/o RPC-Over-HTTP added RunOnce to delete download path on reboot
2.0 – 05/07/2010 – better detection of installed filter packs; uses Filter Pack 2; includes PDF iFilter pack; added disabling TCP/IP V6 option. Now uses BITS for file transfers; added unzip function to unzip the PDF iFilter pack download. Cleaned up some functions. Uses environmental variable “temp” for download location. Checks if things are already installed/downloaded/unzipped before trying to install/download/unzip them.
2.1 – 12/08/2011 – Added the new prerequisite introduced with the release of SP2, IIS 6 WMI Compatibility feature (Web-WMI). This is added to all options containing the CAS role

Code:
