Moving a WINS server's IP address to another WINS server

    I have two WINS servers. The first one has the IP address, and
    the second one has The first server is scheduled to be
    decommissioned. Some clients have only configured as their
    WINS server, and connect exclusively through the VPN, so it's not convenient
    to reconfigure them. My question is, would there be any problem with
    swapping the IP addresses, so that the second server has, and
    after the first server is decommissioned, clients that have
    configured as their WINS server will still be able to find a valid WINS
    server at that address? Would there be any problem if, for example, a client
    registers with the first WINS server when it has, and after the
    swap the second server has this address, so that the server that the client
    is configured to use is no longer the owner of the client's registration?

    Both servers are NT 4.0 domain controllers, and the second one is also a
    DHCP server. Would the IP address swap interfere with either of these

    Alternatively, would there be any problem with adding the
    address to the second server, so that the first server can be retired and the
    second server can receive WINS registrations and queries on both IP
    addresses? I know that there are issues with multihomed WINS servers, but do
    these problems extend to WINS servers that have multiple IP addresses on the
    same NIC? Would the WINS service accept registrations/queries on both IP
    addresses, or just one? If it does accept requests on both IP addresses,
    would there be a problem where a client sends a query to,
    receives a response from, and doesn't accept it because is not in its list of WINS servers?

    Any other considerations/caveats?

  2. I don't think that would be a problem.

    No. WINS/Netbios only binds to the first IP#.
    Just shutdown the first server and change the one-and-only IP# on the second
    server to what you want.
