Hi there,We are planning to have to have three servers farm setup in our environment Server 1 -- application and web front end server Server 2 web server Server 3 database server We have completed installation of sharepoint on this server farm but didnt setup NLB yet on Server 1 and server 2. Can I configure NLB on server 1 and server 2 after installing sharepoint? Or do I need to setup NLB first and then install sharepoint? We are kind of new to this distributed sharepoint server environment, I have the following questions How can I create a new web application in a farm I think from application serverfrom server2 and create a new application and under Load Balanced URL enter the virtual IP address of load balanced configuration. Is it correct? When I do step-1 it will automatically create all the necessary files on our front end web servers?is it correct ? are there any steps involve between ?How can I access this web application? I mean what would be the URL of this web application from the below three URLs? http://server1:portnumber/sites/name/default.aspx http://server2:portnumber/sites/name/default.aspx http://virtualipaddress:portnumber/sites/name/default.aspx If it is going to be (http://virtualipaddress:portnumber/sites/name/default.aspx ) how can I access the second web application when I create it later? what would be its URL ?Any links/posts which is having this information would be very helpful.Thanks,Vaishalivaishu.mspp

Hello Vaishali, I try to include some information for your questions, as below: 1. Can I configure NLB on server 1 and server 2 after installing sharepoint? Or do I need to setup NLB first and then install sharepoint?I dont think its necessary to configure NLB before installing SharePoint products. Regarding your description, you are possibly want SharePoint Web Front-end Server to be load-balancing based on TCP/IP to route requests. To configure TCP/IP Network Load Balancing, please refer to:(KB323431) How To Set Up TCP/IP for Network Load Balancing in Windows Server 2003 http://support.microsoft.com/default.aspx?scid=kb;EN-US;323431 (KB323437) How To Configure Network Load Balancing Parameters in Windows Server 2003 http://support.microsoft.com/default.aspx?scid=kb;EN-US;323437 2. How can I create a new web application in a farm I think from application serverfrom server2 and create a new application and under Load Balanced URL enter the virtual IP address of load balanced configuration. Is it correct? When I do step-1 it will automatically create all the necessary files on our front end web servers? is it correct ? are there any steps involve between ? How can I access this web application? I mean what would be the URL of this web application from the below three URLs? If it is going to be (http://virtualipaddress:portnumber/sites/name/default.aspx ) how can I access the second web application when I create it later? what would be its URL ?There are many questions specific to your environment, I recommend you to refer the following blog to adjust the process to configure NLB:SharePoint Farm, Virtual Server and Network Load Balancinghttp://www.sharepointblogs.com/aaronrh/archive/2007/04/13/sharepoint-farm-virtual-server-and-network-load-balancing.aspx For more information about SharePoint redundancy plan, please refer to:Plan for redundancy (Windows SharePoint Services) http://technet.microsoft.com/en-us/library/cc288334.aspx If you have any further questions about this topic or I misunderstood your concerns, please feel free to let us know.
