FAILED nslookup host.domain

Question

I am performing an R12.2 Vision Installation on SLES 11 SP3 for VMWARE.
Reference RDA - Health Check / Validation Engine Guide (Doc ID 250262.1)
I executed the " ./rda.sh -T hcve " check to perform the Oracle E-Business Suite Release 12 (12.2.0) Preinstall (Linux x86_64).
I receive this failure:   " A03550 DNS Lookup           FAILED  nslookup host.domain "
Can you help direct me to why I may be receiving this error?
more  /etc/hosts  ------My etc hosts I believe is setup correctly.

Hi there
You are executing this:
Platinium2:/pwoll/rda # nslookup Platinum
and you are trying to reach the Platinum2
On the other hand, Just to be sure is your DNS working correctly ?
