Hey guys, I noticed that when I configure the wpad entry in DNS to use the NLB address of the array (internal NLB address) then authentication fails. Does anyone know if this is a doc'd issue? It works find when I configure the wpad DNS entry for the internal DIP on one of the array members. Thanks!
