With a little help from CST (our IT support) and Symantec Ghost Solution Suite 2.0 we've are well on our way to setting up our 19 new computers. The 800+ page implementation guide for Ghost made the project seem more complicated that it really was.
Now that we've successfully created our master image, ran a trial clone, ran a multicast session to clone three additional computers, and did a simple name change and joining to our domain those new computers are all ready for their new homes. I'm looking forward to learning how to use this tool better in the future. It will make the rebuilding and deployment of the computers easier.
The next step is to make an image of the out of the box configuration from HP to have on hand. After that we can clone the remaining machines so they all are identical to one another.
I'm sure there are many ways to configure and push computer configurations out to new clients. For me, Symantec's Ghost Solution has made the process easier. It may be a costly solution to implement for most businesses but with charity licensing the option is very affordable for non-profits.
