sorry to interrupt the flow of the Making the Web Work for You series, but this is somewhat important. Microsoft issued a patch last week for the outstanding .Net issue that could pose a significant threat to those of you with Internet facing IIS servers. Although all .Net systems are vulnerable, the affected IIS boxes do pose the greatest risk for exploit. For some reason the OOB (out of band) patch is only available through MS Download Center.
