SYMPTOMS
When you perform an unattended installation of Microsoft Windows 2000 Service Pack 4, and you configure the DHCPClassID option in the Unattend.txt file, servers that are running Dynamic Host Configuration Protocol (DHCP) do not detect the DHCP values that you configured by using the DHCPClassID option.

If you use the ipconfig /setclassid command to set the DHCP values, this problem does not occur.



CAUSE
This problem occurs because the client computers do not send the DHCP-user-class information correctly after you set the DHCPClassID option in the Unattend.txt file.
