Here is a pointer to information on the subject: http://www.microsoft.com/ntserver/ntserverenterprise/exec/feature/wlbs/ If you have any further questions, please feel free to email me. Thanks, David Whipple. -----Original Message----- From: Nicolas BONNET [mailto:nbonnet@atos-group.com] Sent: Wednesday, December 29, 1999 8:35 AM To: vrrp@drcoffsite.com Subject: Fault-tolerant hosts I make a study on fault-tolerant systems including networking.
