4.Displaying DHCP server activity using Netsh
C:\>netsh dhcp server show mibinfo

5.Authorizing a DHCP server using Netsh

You can use the Netsh command to authorize a DHCP server from the command line. In an Active Directory environment, you must first authorize your DHCP server before it can lease addresses to clients. 
 
For example, to authorize a DHCP server named AAPAC-DHCP-SRV01 in the CONTOSO domain and which has IP address 10.224.34.51, type the following command: 
netsh dhcp add server AAPAC-DHCP-SRV01.contoso.com 10.224.34.51 
 
To verify the result, type this command:  
netsh dhcp show server
 
If you decide later to remove the server from your network, you can unauthorized it by typing: 
netsh dhcp delete server AAPAC-DHCP-SRV01.contoso.com 10.224.34.51
