I'm using WSS v3. I am having a problem where a site is being deleted every night. This site has been up and running for a couple of months with no problem. The web application and site collection configuration are still there. If I look at the Content Database, it says 0 for the Current Number of Sites. I restore the Sharepoint config and the SQL database and the next night the same thing happens. Seems to be happening somewhere between 11pm and 7am.
