Can't find server name

[Joshua Dooney]

When I do an nslookup for the domain sitesuite.com I get a time out.
the name server is called sitesuite.com 

DNS request timed out.
    timeout was 2 seconds.
*** Can't find server name for address 10.0.0.50: Timed out
*** Default servers are not available
Server:  UnKnown
Address:  10.0.0.50

DNS request timed out.
    timeout was 2 seconds.
Name:    sitesuite.com
Address:  10.0.0.50

What have I done wrong?
