  • NLB, yes... HLB depends on the "intelligence"... some will detect outages and correct... others won't.

  • I use Windows NLB with 2 WFEs (make sure the Microsoft SharePoint Foundation Web Application service is running on each) due to the unavailability of hardware load balancers.

    The major downside of this is that Windows NLB isn't application-aware.  If IIS is dead on one of the servers, but the OS is running and the NLB heartbeat is still there, it will still receive requests and the users will get an error.

    In an ideal world I'd have a pair of hardware load balancers :)

  • I'd recommend that you spend a few minutes looking into how HTTP traffic works.

    Long story short, it's possible... depends on how they're configured for failover... might be using NLB, might be using hardware load balancers, might be using reverse proxy.

  • I thought NLB or HLB directs traffic ? I might be confused or don't have a great understanding of it. So with NLB or HLB if 1 of the WFE dies everything will just go to the 2nd WFE ?
