Hello,  I would recommend to open case with support to look into this further.
Hello,       I almost finished the configuration of a new cluster  5 x X400 + 800 SSD, 24GB RAM, 2xGbE, 2x10GbE. OneFS 7.1.1.1       AD in a windows server Windows Server 2012 Std.         Everything looks very well, but  node 3 doesn´t respond any request from the clients to delivering  home folders.  When I want to login from any Mac Client  the home folder doesn´t respond.  It happens in all the home folders coming from node 3. I  tried from the serial console and all basic commands works well. also when i tried a  ping to the node and It answered.  When I  use the WebIU from node 3 I get the message:  Forbidden you don´t have permission to access / on this server.  I can´t find any document in EMC/isilon refered to this error but the  message in the forums shows a Apache error.  Does the Apache configuration needs to be repaired in the local node?           The rest of the nodes answered very well  any time from any client.   I´ll appreciate any comment.
