    Assisted Solution

    Secure Only updates will only allow clients that are domain members register their names in DNS.

    Legacy clients, i.e., Windows 98, NT, will require DHCP to register the names for the clients.

    I should have read your question thoroughly. Is this the only option in the drop-down menu or do you receive an error when you attempt to select something else? Do you have any errors in the event logs?

    legacy clients can't be joined to the domain if DNS is setup to only secure update???

    Accepted Solution

    Legacy clients cannot not join a Windows 2000/2003 domain (more specifically, have a computer account in AD). The use NTLM authentification to authenticate to the domain. When only only secure updates is chosen, DHCP will register the clients in DNS on behalf of the legacy client. This setting is on the DNS tab in the DHCP server's properties.
