Not able to add esxi to Vcenter appliance server

Hello Everyone,

I am facing weird Issue in my lab environment.. I have created two ESX servers esx1(192.168.111.130) and esx2(192.168.111.131) on VMware workstation which is running on Window 7.

I am able to connect to these two esxi servers with help of C# client.

Now I have installed VCenter appliance as VM on esx1. IP of Vcenter appliance server is 192.168.111.128

Now after doing configuring part of appliance server when I connect to appliance server through C# client. I am able to add the esx1 host but not esx2.

esx2 is not pingable from appliance server.

esx1 and esx2 are pingable to each other.

esx1 , esx2 and appliance server are pingable from my Window machine on which I have installed VMware Workstation to set up this environment.

I have rebooted esx2 couple of times and change the IP as well from 192.168.111.131 to 192.168.111.132, but no luck

Any help on the above issue is highly appreciated.

Thanks

Vikrant
