SYMPTOMS
You can use the Ipconfig command to set the Dynamic Host Configuration Protocol (DHCP) ClassID of a network adapter. However, when you use the following command line syntax
ipconfig /setclassid * ClassID
to set the ClassID of multiple network adapters by using the asterisk wildcard character, the ClassID of only one network adapter is set.
