I've got no direct experience about that alert, but the Snort signature database can give you additional information: http://www.snort.org/pub-bin/sigs.cgi?sid=4414 Summary: This event is generated when an attempt is made to exploit a known vulnerability in Microsoft systems using the Print Spooler Service. In particular this rule generates an event when an attempt is made to exploit the function "AddPrinterEx" via the "spoolss" component. False positives: None known. Another reference you may find interesting is the MS Security Bulletin: http://www.microsoft.com/technet/security/bulletin/MS05-043.mspx ciao, ema
