While playing around with one of my PIX boxes, I came across this little syslog daemon for use on W32 systems. It's free for 30 days and it can be used in a number of ways. If you don't need all the features that this has to offer, Cisco provides a similar one for free for use on W32 systems (and *nix too).

NOTE: the doc above describes the service. You need a valid account on the Cisco site to get the download (legally).
Anyway, hope someone else can use the NFO.
