I've installed two snort sensors logging to a MySQL database with
internal storage, using heartbeat, drdb and some hacks, in high
availability. But it runs under Linux. If you are interested, post 
another message and I will tell you how I did it, but you talk about 
Windows, so I don't know if you are interested in the information.

Regards.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
