DNS How-to-speed-up-your-NIC

Hi Experts,

IT is curios!

I tried to copy large iso files from local harddisk to vmware vcenter computer. bandwith is very small 1 MB/s ?
We have 2 active directory integrated DNS Server and a secondary DNS Zone on memberserver. dhcp arrange dns-, wins options ect. well without errors.
So i change my IP-Connection from Wlan to Ethernet Controller an get a new IP Adress. I command <<ipconfig /flushdns && ipconfig /registerdns>> on vmware vcenter computer but can't ping my new IP Adress in fact it caches my old IP Adress. i inspect the two ad dns server and find out that dns replikation seem not be finshed. I load master dns zone manually on dns server which dns forward zone miss my A Record. On vmware vcenter computer i restart dns-Client net stop && net start dnscache. Copying files now works fine with 20MB/s.
I wondering why i. AD DNS does't refresh my A Record and ii. which slow name resolution appears if DNS does't work properly? NetBIOS. Is Netbios slower than DNS in SMB issue?

Thx && Best Regards.
