On my network, I currently host multiple different domain names on my own DNS server internally. Each of my machines internally have public ip addresses which are assigned via my DHCP server. I am pondering installing ISA server, but I see it wants you to use private IP addresses internally. I have no problem doing this but INTERNIC is point to both my internal primary dns and secondary dns for resolution to my internal websites / ftp sites, etc. I am having a real difficult time understanding how the dns portion is going to work. Anyone out there will to spend a few minutes with me either through ICQ or somthing to answer some questions. Since this is difficult to implement in a test environment and then rollout to production, I want to make sure it is done right the first time to eliminate downtime. Thanks in advance for all your reponses. Steve Groner LANI.COM
