XMPP server software recommendations [closed]
I would suggest Openfire http://www.igniterealtime.org/projects/openfire/index.jsp
I have used Openfire on both Windows and Linux for the last year and a half and it has been a rock solid jabber server.
I like ejabberd a lot; it just works. It is even easy to migrate from jabberd. Don't know how/if it runs well on Windows though, I use Debian GNU/Linux.
