Samba problem - addl note

Some additional notes on "Strange Samba problem"... - When booting Linux, when listing activity to the screen, the following occurs... Mounting SMB File System ..... unused I would assume this would normally be "done" like most other items. - I also noticed, while browsing Yast software install and remove, that Sendmail was installed on Saturday morning. It's listed in Yast as a "Red Hat" distribution. Our office is closed on Saturday. Could this be a sign of some sort of intrusion?? Matt
