Unable to Ping ESXI 5.5 Host

Image
while i am continue working on my  Lab and configure ESXI i faced another problem and took 2 days to solve it maybe someone faced this issue but this will help other people as well.

The problem description like this :- after assigned IP to the server i want like normal people connect to this server using my laptop but simply when trying to ping :-

"Detestation unreachable" 

I thought at first it was my network card issue and maybe it's not supported By ESXI, But this is not valid option because the weirdest part in this issue was when restart the server and ESXI loading the services i was able to ping without any problem then the message appeared again.


as you see from the above screenshoot ping then not ping !!!!!

The solution very simple i start missing with BIOS options and found new option there called "Network Stack" all you have to do is enable this option and link to IPV4.

Happy new year and healthy 2015.

During the Holiday I was working on my mini Lab and Upgrading the Server i want to use ESXI 5.5 this time,usually the built-in Ethernet card  Intel or Realtek ( Mine ) while the installation i faced an issue that ESXI 5.5 doesn't identify my Ethernet card and the installation failed.

To solve this issue the normal ESXI iso will not work, because of this you have to create something called ESXI custom ISO using Software called ESXI customizer.

Download it from here.

You make this software work you need to install the original ESXI ISO.

Download it from here.

and The most important thing which is the driver that you need it for Ethernet Card, the driver usually depend on the PC just like to told you before I am using Realtek and you can download :-


net-r8168+r8111e From here.net-r8169 From here.
Now you have all the software,  Original ESXI , Driver and the customizer. Open the ESXI customizer new GUI screen will be open with three box like the below…
