  • Changing the Subnet in a Windows 2003 Environment

    Hello All,

    I'm a consultant and one of my larger clients had their original servers setup by another company and unfortunately their subnet is 192.168.1.0/24. I'm having major problems with DNS resolution for remote users whose home network has the same subnet (i.e.: our server is 192.168.1.1 while their home gateway is the same!).

    My question involves changing the subnet in a Windows 2003 environment. We have about 10 servers, 2 of which are domain controllers and DNS servers. We have one router that is also a firewall. Pretty basic setup: servers have static IPs, clients have dynamic, DHCP is given by a DC running DHCP,

    Is it a simple task to change the subnet to, say, 192.168.200.0/24 ? Other than DHCP, DNS, and the firewall settings, what else should I be aware of. Is this too ambitious of a project?
