Well DNS seems ok. The name is resolveable at both locations to it's actual IP address which is 10.30.1.28.
So on my PC if I go to http://10.30.1.28:9084/vci/downloads/vmware-umclient.exe I get "Oops! Google Chrome could not connect to 10.30.1.28:9084
On the vcenter server itself if I go to http://10.30.1.28:9084/vci/downloads/vmware-umclient.exe, I get HTTP ERROR 404
Problem accessing /vci/downloads/vmware-umclient.exe. Reason: not found
Powered by Jetty://
So the windows firewall is turned off on the vcenter server to rule that out. Now is there an access list or configuration for Jetty that may be blocking access?
