I am using bind 9.6.1 and about 2 days ago I realized that there is a bug at bind for windows platform. when server gets "UDP client handler shutting down due to fatal receive error: host unreachable" error. it stays alive but no response for after dns queries. then I need to restart it manually to make it responsive(I put a task for this issue from windows). I cant use microsoft windows dns server because I am using windows 2008 server web edition which does not include that. so my question is what are the other solutions you use for dns server in windows ?
