DHCP Information

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.
