RPC failure for hostnames with multiple DNS entries

    Question

  • I'm using MAP Toolkit 8.5 to scan by IP address range, for a narrow range of IPs used on a VPN.

    The plan is to have mobile workers' devices attached to the VPN at a specific time and run an inventory.

    When workstations connect to the VPN, they register their IP address provided by VPN, but simultaneously register their WiFi or mobile network IP address that they're using to connect to the Internet and on to the VPN.

    This creates a problem during inventory and gives the error "Failed - RPC Server Unavailable", yet if I use wbemtest I can make a successful connection by the VPN IP address of the workstation.

    If I manually remove the second DNS entry registered by the workstation, the inventory works.

    So are there any tricks to make the MAP inventory "prefer" one particular subnet of IP addresses when it does a DNS Lookup for inventory, or any way to make this work without changing the VPN infrastructure? I don't really want to make wide-spread changes to the way ALL workstations register in DNS for the sake of a simple scan by MAP. I'd like to fix this at the MAP server end if at all possible.

    Thank you
