I have inherited a Casper system for 150 or so clients , and this is my second week of using Casper. (So, this is a real beginner question.)
The naming convention for our clients needs overhauling. I have successfully used these excellent instructions to rename one client. So far so good.
But is there anything that I should be concerned about when renaming half of the clients in our system?
 Updating the Computer Name of Client Computers:
When I rename clients, I go ahead and unbind from our AD, rename then rebind. I try to keep AD as "clean" as possible...
We used pre-stage imaging to rename a group of computers this summer for distribution, but we also imaged them. Not sure if pre-stage would simply handle the naming or not... then it should be a matter of just running recon on the computers to update the JSS database.
