I'm looking for a free (GPL or BSD) and lightweight DNS server that runs on Windows, which I can use as a server for my coLinux installation, which, when configured via slirp, always gets the Windows server as it's only DHCP-assigned DNS server (I can't hardcode it in colinux as something like 4.2.2.3, since I often travel to places where outgoing DNS is blocked, and I want whatever rules are configured in Windows to be used for the linux process as well).
Bonus points [virtual points, that is...] for something that's portable.
