There is some hazy areas in Net::DNS. Neither I nor the original author have access to a windows machine, and there are some questions that we need to get answered. See this RT ticket for the background.
Basically, the questions are:Net::DNS is used behind the scenes in several popular perl applications (SpamAssassin comes to mind). Net::DNS needs to run better on windows, and I can't do that without people's help. So if you know the answers to those questions, or you have the means to find out, please contact me.
