How to Configure DHCP Class ID on a Windows 2000 DHCP Client

This article was previously published under Q235272
Windows 2000 DHCP clients support DHCP Class ID options. You can configure this feature by using Ipconfig.exe command-line switches.
To set and enable DHCP Class ID on a Windows 2000 DHCP client, type the following line at a command prompt:
ipconfig /setclassid ADAPTER_NAME CLASS_ID_TO_SET
If ADAPTER_NAME contains spaces, enclose it in quotation marks. For example:
ipconfig /setclassid "Local Area Connection" teamnet
To clear and disable DHCP Class ID, leave CLASS_ID_TO_SET blank:
ipconfig /setclassid ADAPTER_NAME
To query:
ipconfig /showclassid ADAPTER_NAME
More information is available by typing ipconfig /?:
