Ny DHCPd/BIND9 kombination does exactly what you mean. Existing zune entries are not changed by DHCPD, because DHCPD only adds new "unknown" Entries to the DNS database, or changes dynamic entrioes which have an existing DHID record set. If i try to use a name that is already set manually as a static entry, DHCPd throws an error to the logs like: "Record already available and no DHCID record foung, NOT mine!" Is this the behavior you want? I have set 'ddns-update-style standard' in my dhcpd.conf and it works well. Regards, Dirk -- Dirk Gottschalk Paulusstrasse 6-8 52064 Aachen Tel.: +49 1573 1152350
