The following script will connect to a list a servers provided from a text file, it will return the disk size and free space of the drives. It will create a HTML report and email the file. You must create a file with either the name of the servers or IP addresses line by line. Within the script there are a few variables that will need to be modified, and some varibales to change the look of the HTML report.
