I was able to complete a successful install of VMware-vCenter-Server-Appliance-5.1.0.10100-1123965_OVF10.ova. I was able to login into VMware vCenter Server Appliance web page port 5480 and VMware web client at port 9443 and with vClient. All service are working properly. To me looks like a good install.
Then I encountered a host resolution error when using "Add a host wizard" in the vsphere client to add a host using its HOST NAME (not IP). It resulted in error when putting the host name instead of IP address. Here is the exact error and article associated with it: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1027672
I read the articles and made sure that I followed directions to fix this issue. My DNS is properly responding and resolving and I can directly login into the actual host name itself using vsphere client. The lock down mode is disabled. Besides this host name problem, I can create a host using its ip address but that is not my objective. I want to add a host using its host name. Any suggestion is appreciated. See image attached.
