We have a network with one windows 2003 server acting as DC, DNS server, Terminal Server and DHCP server.
Problem is after our isp changed the internal IP address of our router we had to change the IP of the DNS server. Since this happened noone can browse the network through network neighbourhood. Also I cannot add any users/ computers to the domain through their control panels. nslookup fails saying "cannot find server for address 192.168.0.3: non-existent domain"
It then forwards this to our isp dns server which also says non-existent domain.
Any help would be appreciated.
Is it possible to back up all users and computer accounts etc from AD then delete AD, uninstall DNS and start again?
