DNS and WINS Information Sometimes Cannot Be Customized When Using File > Import
Details
If you choose File > Import to convert a Windows 2000 physical computer with no service pack to a virtual machine and if the IP address of the DNS server or WINS server has a 0 octet, you cannot specify DNS and WINS information.
This is due to a WMI bug.
