I have done the following:
I change the TTL to 86400 which is more higher than the previews one
2- I remove the dkuug.dk, which is not use any more.
I mean by "I ask another client", the machine that is a clint to my dnsserver, any way I still have the update problem, which is when I edit the /etc/namedb/zone.netman.dk and the "/etc/namedb/db.172.16.0" and add a hostname to thos files and restart the named, I can lookup for the new added hostname just on my dnssever, but when I login on another mchine on my network, and try to lookup "using nslookup or dig" to the new added machine, still can't get answer from the dnsserver
