I need to set up a new server for our latest offering (a virtual plan with 30 IP's, on 30 Class C's, with 30 nameservers). Unfortunately, the list of new domains purchased as nameservers came back as all upper case. Makes it a total PITA since the control panel for the server won't accept all caps in the user names.
This will make a long job even longer.
Then I found
