Step 6: Export the new DHCP server configuration information
Run: netsh dhcp server dump > C:\win2012R2dump.txt
650) this.width=650; "height=" 216 "title=" image "style=" Border:0px;padding-top:0px;padding-right:0px;padding-left : 0px;background-image:none; "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/6D/DF/ Wkiol1vua3pz6dnuaadprlz-r8s096.jpg "border=" 0 "/>
To view the exported DHCP information
650) this.width=650; "height=" 257 "title=" image "style=" Border:0px;padding-top:0px;padding-right:0px;padding-left : 0px;background-image:none; "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6D/DF/ Wkiol1vua3oig1sxaafgysmawxm933.jpg "border=" 0 "/>
Step 7: Build and execute the changed DHCP configuration file on the old DHCP server Dhcp.bat
Create a new Notepad on the old DHCP server and change the suffix name in the form Dhcp.bat
650) this.width=650; "height=" 285 "title=" image "style=" margin:0px;border:0px;padding-top:0px;padding-right:0px; Padding-left:0px;background-image:none; "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6D/E3/ Wkiom1vuadngcdayaafhwkyxn6s238.jpg "border=" 0 "/>
Copy the first 5 lines of the old DHCP configuration file into the Dhcp.bat file, replace add with Del, and add Netsh before each line of DHCP, with the following effect:
netsh dhcp Server 192.168.1.105 Del class "Default Routing and Remote Access category" "Remote access Client user class" 525241532e4d6963726f736f6674 0 B
netsh dhcp Server 192.168.1.105 Del class "Default BOOTP category" "BOOTP Client User class" 424f4f54502e4d6963726f736f6674 0 B
netsh dhcp Server 192.168.1.105 Del Class "Microsoft Windows 2000 Options" "Microsoft Vendor specific options for Windows 2000 clients" 4d53465420352e 1 b
netsh dhcp Server 192.168.1.105 Del Class "Microsoft Windows 98 Options" "Microsoft Vendor specific options for Windows 98 clients" 4d534654203938 1 b
netsh dhcp Server 192.168.1.105 del Class "Microsoft Options" "Microsoft Vendor specific options for Windows 98 and Windows 2000 clients" 4d534654 1 B
Copy the first 6 lines of the new DHCP configuration file to the Dhcp.bat file, replace the computer name or IP address with the old DHCP, and add Netsh before each line of DHCP, with the following effect:
netsh dhcp Server \\192.168.1.105 Add class "Default Routing and Remote Access class" "Remote access Client user class" 525241532e4d6963726f736f6674 0 B
netsh dhcp Server \\192.168.1.105 Add class "Default network Access Protection level" "Default special user class for restricted access clients" 4d5346542051756172616e74696e65 0 B
netsh dhcp Server \\192.168.1.105 Add class "Default BOOTP Class" "BOOTP Client User class" 424f4f54502e4d6963726f736f6674 0 B
netsh dhcp Server \\192.168.1.105 Add Class Microsoft Windows 2000 Options "Microsoft Vendor specific options for Windows 2000 and later clients" 4d53 465420352e30 1 B
netsh dhcp Server \\192.168.1.105 Add Class "Microsoft Windows 98 Options" "Microsoft Vendor specific options for Windows 98 clients" 4d534654203938 1 B
netsh dhcp Server \\192.168.1.105 Add Class "Microsoft Options" "Microsoft Vendor specific options for all Windows clients" 4d534654 1 b
Double-click the Execute Dhcp.bat file, in order to see the execution process, you can execute cd\--dhcp.bat at the command line

Copy the old DHCP exported file dhcp.txt to the new DHCP server and import the modified DHCP configuration information on the new DHCP execution
netsh dhcp server import c:\dhcp.txt
