no i cannot connect to the host.. i give static IP ..and both machine are pinging to each other... but when i try to connect the host network error shown

[vJJSosa]

if you have proxy settings, try to disable.

if you open a browser and navegate with the IP Host, can you see the host portal?

Are you using dns or ip for this test?

[Viveik24]

no sir i didn't use DNS

through IE i able to open the Portal

[vJJSosa]

are you able to connect the laptop directly in the esxi?

[Viveik24]

Sir now i explain you what i did...

on HP Z400 Workstation (8 GB Ram, Quad Core Processor & 250 GB HDD) i install ESXi 5.1

I gave 192.168.1.15 IP to host and Default Gateway as same

Install Vspere clinet on my laptop (Dual Core, 2 Gb Ram 320 Gb Hdd) and IP is 192.168.1.5 , default gateway is same

but when i try to open Host through Vsphere Client it shown Connection Error...

[vJJSosa]

is so strange... please check this KB VMware KB: Diagnosing the vSphere Client when it fails to connect to an ESX/ESXi host or vCenter Ser...

in adition, check if you don't have duplicate ip in your network, and try to use the same gateway for both devices

[Viveik24]

but i want to ask is router is necessary to connect Esxi host to Vsphere Client..???

[vJJSosa]

is not necessary if you have a single network(if you use the same network for both devices), you can leave the default gateway blank if you want

[Viveik24]

ok i'll do that

but if u dont mind can u please suggest to how should i re setup my Virtualization lab at home..

[vJJSosa]

from the console of the esxi (DCUI), navigate to "Reset system configuration" and reboot the host. Then you need to set up the host again.

VMware vSphere 5.1

Can you please check the firewall settings to see if firewall is blocking the connectivity.

Please check this KB as well - VMware KB:    Cannot connect to the ESX/ESXi host or add it to vCenter Server 

Also, it would help if you can provide more details regarding the error message that you are seeing when trying to connect the ESXi standalone host.

Regards,

Amar

Also, Check that Port 903 must be open between the vSphere Client and ESX / ESXi hosts.

The vSphere Client uses this port to display virtual machine consoles on ESX / ESXi hosts.

Vsphere Client could not connect to "192.168.0.101

An Unknown Connection Error Occurred. (The client could not send a Complete request to the server. (The Underlying Connection was closed. An Unexpected error Occuredon a send.))

This seems to me to be some kind of network-related problem. But definitely you do NOT need router to connect to ESXi-server. I have backup-ESXi at home and I can connect to it from my PC (both on the same physical switch). I do have router for internet-access but it is plugged in one switch-port, so it does not stand in way for PC<->ESXi connection...

All I can recommend is to check low-level network traffic. Use netcat, wireshark, or some other network-sniffer. I think vSphere standalone Client uses TCP for connection, so check if "3-way handshaking" is completed (I suppose not). You can also try "ping" (or "traceroute") again, but not with ICMP. Try UDP/TCP protocols...
