How to export and import DHCP reservations

[David Bui]

My company will change the network mask from 24 to 22 bit
mask and we have more than 100 reservations. I'd like to
know how to export/import all the DHCP reservations
without having to manually recreate them. Or is there a
better way to do it rather than export the reservations
and then delete the dhcp scope and then import them back
in.

Thank you

Dave.

Here is something you might want to try:

Use netsh to dump the existing information.

netsh dhcp dump > dhcp.txt

then modify what ever is needed.

then to reload then do a netsh -F dump.txt

Make sure you test this on a test server, but you can do alot of things with
Netsh. If you want to explore do a netsh from a cmd prompt then keep typing
in cmds as you get deeper and deeper.
