am workng with this guy who does some unusaul stuff not saying they are right or wrong but unusual...
On a Windows 2003 server DHCP s set on the Pix firewall giving ips to all the client computers one of the DNS is set for our internal DNS whch is the same as this server which s also the DC server the other is an external DNS server for our ISP all client computers have both the internal and one external DNS configured on thier machines.....
in the internal DNS a host record is set for our hosted smtp server mail.ourdomain.com ip address 55.555.454.45
now this seems to work if we have to change smtp we just change the ip address in the host record.
we also have host set up for our outside www. and ftp and other hosted servces..
our forwarders are also set to the isp external dns servers..
my queston I was taught to set up the internal dns with forwarders and thats that what if any problem is there with settng up the DNS with all these external records and these configurations in general.
Also due to the fact this is problaly a smple queston when change ISP once you have everything set up and check the DNS and it fails recusve is this becuase of the root and how can you fix it.
