    Unicast and destination host host unreachable.

    Terminal Server Configured to NLB with Unicast.
    Server functioning is working properly but when we connect to NETWORK
    LOAD BALANCING MANAGER
    When it try to other node it showed destination host unreachable,
    error connecting to "2ndHOST NAME".
    Can some one tell me what is missing here?

    Re: Unicast and destination host host unreachable.

    Do you have a second NIC configued as the management interface?

    Management interface ? You mean for heat beat ? Yes with a cross
    cable . I can ping Private and Public IPs from each nodes.

    The Ip config like this

    ***Node A

    *NIC 1
    10.198.X.18/24
    GW 10.198.x.125
    DNS 10.198.x.60

    **NIC 2
    60.60.60.60/24
    GW none
    DNS none


    ***Node B

    *NIC1
    10.198.X.19/24
    GW 10.198.x.125
    DNS 10.198.x.60

    **NIC 2
    60.60.60.61/24
    GW none
    DNS none

    A 'common misperception' with NLB clusters. Heartbeats and crossover cables
    do not apply to NLB Clusters...only to Server Clusters. So, I would connect
    those second NICs to a switch, give them some addresses and use them as
    Management interfaces for you NLB cluster.

    Re: Unicast and destination host host unreachable.

    Thank you very much for the Answer. It makes sense to me. Instead of
    management port Can I add additional connection (get removed from
    Heartbeat) to same router which other port is connected and make a
    Teaming and configure servers with NLB. This server is in Trusted and
    users are connected by VPN. As this is in Trusted we can use to manage
    from Trusted.

    Re: Unicast and destination host host unreachable.

    Make a connection to the switch using the NICs that had been connected via a
    crossover cable, assign IP addresses and use those NICs for management. Do
    not use NIC Teaming for NLB.....unless, of course, you like 'pain'. So, you
    will be loading balancing VPN connections? Or, what service(s) are you load
    balancing?

    Re: Unicast and destination host host unreachable.

    Thank you for your information. We are load balancing the entire 3389
    load which coming for Terminal Server.
    What we was looked for High availability for our Terminal Server. But
    realize Majority Node Cluster doesn't fictional with Terminal servers
    and thought NLB will be idle.
    Enabled the Session Directory also. Anyway thank you very much for
    your great help and its working fine now & highly appreciated.
