    Hi Zafer,

     

     

    If the response isn't coming back from the server, you could start at the server and work your way towards LTM to see where the reply is dying.

    Can you confirm that the cluster IP should actually respond to ping? Have you pinged it successfully from other boxes?

    Hello

     

     

    Microsoft Cluster on works on production . we can ping it from everywhere except bigip units.

     

    i found information about Microsoft. Microsoft cluster works on multicast.

     

    i disabled auto last hop

     

    added static arp

     

    enabled multicast ......

     

    but still does not work

     

    you can get info from this link
