Thanks Till! You guys are best! I saw the New Slave in the DNS Manager but I imagined I would have to do some major config file surgery in order to get 2 boxes to connect. After searching for couple hours I found this by Falko http://www.howtoforge.com/ispconfig_dns_godaddy
So I went straight to ebay and placed a bid on a box and won it for $150
I can't wait to get it and install perfect Ubuntu with ISPConfig. HowtoForge is great, Ubuntu for life. Can I make the new box ISPConfig3 and get the slave DNS feature to work or is that not supported?
