      He's scientist that's why

      ok try clearing the cache ipconfig /flushdns and then disable dns client service

      Resolves and caches Domain Name System (DNS) names for this computer. If this service is stopped, this computer will not be able to resolve DNS names and locate Active Directory domain controllers. If this service is disabled, any services that explicitly depend on it will fail to start.

      This is the description

      so it shud happen ideally and if not the we will take wireshark trace to check who is doing resolution. okaaa mera baooo

        It doens't make sense to disable those services when connected to the internet.

          Re: Disabling DNS Name Resolution

          bcoz i had always thought that DNS client is the service in windows Responsible for DNS Name Resolution ... but ... when i tried it by disabling the DNS client service , the systems still performs name resolution although now there is no DNS client cache ( resolver cache ) on those systems .. neither they are capable for DDNS updates

                Hey v-2nas , we had already tried this ? Get some nutritious food mate that cud light up U

                meanwhile if we disable the DNS client service , nd then we try to clear cache ,
                that wud prompt an Error ( bcoz now after disabling there is no subsystem for getting cached dns names )

                Don,nt get this

                  we didn't try that all the time we were doing nslookup but not with ie i read on on site that it uses different dns libs

                    Re: Disabling DNS Name Resolution

                    after munching bit of baked soyabeen specially imported from batala i got this

                    NSLOOKUP is that it does not test the DNS Client component on the DNS Client. NSLOOKUP uses API Calls directly through Winsock, or the TCPIP Stack to resolve names, it does not use the “DNS Client” Service to handle Name Resolution.

                    When using NSLOOKUP the default DNS Server it tries to connect to is the DNS Server configured on the system NSLOOKUP is being run on.

                    hope this answer gives u some relief.
                    Thanks & Regards

                      Re: Disabling DNS Name Resolution

                      so in the end we conclude that , dns name resolution is not provided DNS Client service but by the TCP/IP Stack itself by contacting the preferred DNS Server .

                      so windows dns service DESCRIPTION got me wrong
                      " Resolves and caches Domain Name System (DNS) names for this computer. If this service is stopped, this computer will not be able to resolve DNS names and locate Active Directory domain controllers. If this service is disabled, any services that explicitly depend on it will fail to start. "


                      now how can i provide u REPS v2-nas

                          Re: Disabling DNS Name Resolution

                          u need to read the answer correctly.

                          nslookup is troubleshooting tool and it doesn't test DNS client service component

                          dns client service would be used by apps like ie firefox (jalti lombri)

                          does it ring the bell heer de mame

                            mate , this simply means that TCP / IP Stack is being used for name resolution nd dns client service is being for caching , nd updating ddns hosts with ad domains
                            Can,nt u get it nd stop crapping
