  • 1.  Cannot add a host with host name in VC

    Posted Oct 29, 2011 03:28 PM

    Hi all,

    Good Day.

    I just finished installation of 2 esx4.0 servers, Vartual Center Server and Domain controller server in my test lab in my home. i added esx server host records in to DNS as well. then i tried adding hosts in to VC using host name, then I am getting error like

    "cannot contact the specified host(xxxxx). the host may not be available on the network, a network cofiguraion problem may exhist or the management services on this host may not be responding"

    I have checked that all are pinging and no network configuration issues found. I am able to add a host using IP address but not with host name. I have checked the services in VC, all services are running fine. Earlier I never had this issue.

    Please help me if any one has the solution.

    Thanks in advance

    Regards,

    Suresh

    Even though you say DNS should be ok, please double check all settings.

    • from the vCenter Server run "nslookup vc" and "nslookup esx42". Do these commands return the FQDN and the correct IP address?
    • on the ESX hosts (vSphere Client) make sure the network settings (Configuration -> DNS and Routing) contain the correct information (IP address, subnet mask, gateway, DNS domain, ...)
    • from the ESX host's console ping the hostname of the vCenter Server (short name and FQDN should resolve correctly)
