I’ve been sitting on this post for a long time, and intended to write a more detailed description.
Here are some things you may need to consider (outside of the obvious like DHCP scopes, DNS server settings, Firewall settings & rules, etc) when changing the IP range your Windows network operates on:
- TCP/IP Printer ports on print server
- Printer/Copier IP/DNS/SMTP settings
- Exchange allowed relay ranges
- Any copy/print accounting devices attached to copiers
- Monitoring host settings. Eg. Big Brother/Hobbit – Both client and server side, if not configured to use DNS in config files
- Server iLO IP addresses
Some steps for changing domain controller IP addresses. Do these first before any other important servers:
- Change IP
- ipconfig /flushdns
- ipconfig /registerdns
- Either restart the Netlogon service, or run ‘nltest /dsregdns’
Disclaimer: This is by no means a complete list. Use these directions at your own risk.
