Export DHCP Reservations with Mac addresses:

I had difficulty recently with our DHCP reservations, namely i coudnt export the MAC addresses included in the reservation and the mmc was only allowing very limited as I could only export the ip address and the FQDN of the computer owner.

After a bit of rummaging i found an entry for DCHP in netsh. I found that you could dump the DHCP server settings to a text file. This included every server setting aswell as the reservations. I then filtered the exported file for “Add reservedip” using the find command to export a csv file with just the reservations.

Once i had the file in csv, i simply imported it into an excel sheet using spaces as the delimiter and hey presto a lovely little reservation report:

Same rules as always, dont run it from a UNC path, copy it local to the DHCP server and run it there.

netsh dhcp server dump >> reservationdump.txt
find “Add reservedip” reservationdump.txt >> reservations.csv

You can download the script as is here:
