  • For starters, if you have Exchange 2007, you do not have a CAS Array.  You may be using Windows NLB for load balancing.   Can you clarify which version of Exchange you have?  Open up the Exchange GUI and click on Help - About Exchange Server.  Reply back with the version you have.

    If it is Exchange 2007, more than likely you are using Windows Network Load Balancing for these servers. 

    If it is Exchange 2010, then you can use this page to help remove a node from the CAS array - http://technet.microsoft.com/en-us/library/dd351108.aspx 

    Hope that helps.

  • If you want the server completely removed from Exchange so that you have a single Hub/CAS server, then I would first remove it from the NLB.  Then uninstall Exchange.  One thing to watch for is that any of your Web services (OWA, ActiveSync, Outlook Anywhere) might be going to the NLB address (IP and name).  Keep this in mind if you are going to remove the array as well.

  • hi

    we have exchange 2007 sp1 and yes we have created through NLB. so if i want to remove it should i delete it from the Windows NLB. once the nodes has been removed from the NLB both CAS/HT server will be acting as a single server.

    regards

  • Hi Devang Patel,

    JFYI: HUB server does not require NLB.. if we have more than one HUB server in a site they will be sharing their load automatically. 


    Thanks & Regards, Kottees **** Please mark as an answer if it is really helps you.

  • if it's exh2007, it would be NLB( not CAS Array), just remove the node from NLB, unistall Exchange 2007

    if it's exh2010, once you create CAS Array, automatically All CAS Servers will be added on particular AD Site, so if u have  3 or more CAS on same site , you can't just remove one CAS Servers from CAS Array.

    if it's exh2010, only two Servers are on CAS Array, just remove CAS Array( http://technet.microsoft.com/en-us/library/dd351108.aspx ), unistall secound CAS Servers

    cheers
