I came across a recent little command that helped me out a lot. I was trying to determine all of the information of a DHCP server that had multiple reservations. Now, I could use the management console and just export the IP and reservation name. But this did not give me the MAC addresses or any additional information. I also wanted to just have the basic info of the DHCP scope. So, after some searching I found a fairly easy way to do it. I ran the command:
netsh dhcp server dump >> C:\DHCP_Info.txt
This created a file DHCP_Info.txt in the root drive that contained all the information i needed. I just had to parse the section that listed reservations and import it into a table.
