After reading that experiment in which someone used a bunch of cheap celeron boxes with WLBS and CF professional to cluster, I did some reading up on WLBS. WLBS is what it is called on NT4. It is now NLB of Windows2000. It is free on NT4 Enterprise, or Win2k Advanced Server. I don't know how much it costs, elsewise. Drawback: it only works at the stack level. As someone stated, if your web server (IIS) is in lala land, but still returning pings, WLBS will continue to make requests. You have to get a third party service monitoring system that will run a command line command to turn off the WLBS. This is documented in Microsoft's knowledge base. http://support.microsoft.com/support/kb/articles/Q234/1/51.ASP WLBS is not intended to work with SQL server, file serves, for example. For this they have another product, MSCS (Microsoft Cluster Service). The link below is an overview of MS Clustering in general that I found very useful: http://www.microsoft.com/ntserver/ntserverenterprise/exec/overview/clusterin g/default.asp Matt ------------------------------------------------------------------------------ Archives: http://www.eGroups.com/list/cf-talk To Unsubscribe visit http://www.houseoffusion.com/index.cfm?sidebar=lists&body=lists/cf_talk or send a message to [EMAIL PROTECTED] with 'unsubscribe' in the body.
