use latest git, it includes a dnsseed.
the last one I found is 0.6.3 if I'm not mistaken. But it is the one which writes me out of sync. If there's a newer version compiled for win platform, I would be very grateful to get the link to it. Meanwhile I'm using direct transactions to burse, so not really in need for offline wallet. But may be comes time to store some coins locally

figroll is maintaining the winblows build, drop him a PM.
