Yes, NLB does not control the apps. However there is a utility/service called HTTPMON which controls the web service: http://support.microsoft.com/?kbid=259651 Cheers.

We are setting up a system that has two W2K3 servers configured to utilize Microsoft NLB. Does the NLB logic to determine if a server is "available" for connections take into account the port of which the client is trying to connect on? Say they are web servers and the WWW service crashes on one but the server is otherwise running, when a browser is trying to connect via the NLB name, is it possible for it to get routed to the server where the WWW service is down? The same for other custom apps, if it isn't running on one of the servers and the client tries to connect via NLB name and port, will the NLB logic try to connect it to the server where the app is down and therefore has less network connections? -- Thanks, Scott D. ************************************************ SBC SITES ONLY GOOGLE SEARCH: http://www.F1U.com ************************************************ For Archives, RSS, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link: //www.freelists.org/list/thin ************************************************
