DNS Timeout

Hi,

I'm having DNS timeout and intermittent internet connection in my virtual Machines. Here is some dignostics:

nslookup internal.cloudapp.net
DNS request timed out.
    timeout was 2 seconds.
Server:  UnKnown
Address:  10.20.2.4

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out

nslookup microsoft.com
DNS request timed out.
    timeout was 2 seconds.
Server:  UnKnown
Address:  10.20.2.4

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out

I've tried resizing as suggested below but that did not help.
