You should be able to connect via the DNS name (as you were doing
previously); you just need to ask the server for the members of the
NetBIOS domain (rather than the DNS).  This would look something like:

    // connect to the server using the DNS domain name
    ServerManagement mgmt =
            new ServerManagement("mydomain.mgsft.test", auth);

    // ask it for the members of the "MYDOMAIN" NetBIOS domain
    ServerInfo[] info = mgmt.netServerEnum(1, ServerConstants.SV_TYPE_ALL,

If you aren't able to connect directly using "MYDOMAIN", the above
should work (since your previous trace was able to connect to
