Hello Jim,

Thank you for your post. This is George and I will be assisting you in this
post.

Please note, change IP network scope will be a very complicated project.
Try some other way if this is not necessary because changing IP network
scope will bring some risk.

Here are some suggestions for your reference.

Important notes:

1. Backup all the DNS and DHCP servers before you make any changes.

2. Please schedule non-business time to perform the IP network change. Make
all these servers offline before making any changes.

3. Related services such as RRAS, ISA (or 3rd party firewalls), etc, should
be adjusted.

Suggestions:
==================

1. Unauthorized the old DHCP server if it has been authorized before.

2. Delete old DHCP scope and then build the new one. You should use the new
network ID when you build the new "DNS Reverse Lookup Zone". Change the
DHCP and DNS server to the new IP address manually.

Please note, the old records in DNS server may last for some time, you can
delete them manually.

3. Change the IP address and DNS server address of Domain Controllers.
Reconnect Domain Controller to the network, restart the Net Logon service
or restart the Domain Controllers.

4. Re-authorize the DHCP server if necessary.

5. Renew IP configuration on all the workstations manually, by using
"ipconfig /release" and "ipconfig /renew". Then re-register all the
workstations' IP address in the DNS server by using "ipconfig /flushdns"
and "ipconfig /registerdns".

You can accomplish this by simply restarting all the workstations.

6. For some shortcuts, or other related applications settings that locate
target computers using their IP address instead of using FQDN, please
adjust them manually.

I hope this can you. If anything is unclear, please feel free to let
me know. I look forward to your reply. Thank you.

Sincerely,
George Yin
