Hi Camero

Thanks for the reply.  I did come across on the reverse lookup, but never set it up.  I have updated DNS server so forward lookup and reverse lookup return the same. 

Nslookup vc651.domain.com returns 192.168.1.133, and nslookup 192.168.1.133 returns vc651.domain.com

Performed the installation again, same error....The same vAPI error and 1603 error...

I looked at the logs, can't decipher what went wrong...

Thanks,

-Ken
