Hi Jay... The logs files are being created properly. I can view they using Notepad wiwhout any problem. Well the account that i´´m using is the administrator of the machine where the logs are. And the user can read and write on the directory and files. The event log that are you talking about is the event viewer??? Well...There is a event there... ISA report generation error: 'C:\Program Files\Microsoft ISA Server\ISASummaries.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides. That´s the event. Something strange is that ISA Server is installed on the D: volume... But i really don´t know why it´s giving this error... Thanks, Kiko
