Kiwi Syslog Server is a great little application for those that need a more robust syslog server to run on a windows platform. I have run it for several years now and it is top notch.
I would also recommend Kiwi CatTools which is a great little utility for pushing configuration changes out to Cisco Routers and also for backing up the configuration on a regular basis. We do backup's daily of our router and switch gear and CatTools sends us an e-mail report of what changed, what wasn't available and if everything backed up just fine. Great, great tool.
