ESXi, ping issues..

ESXi 5.1.0, I've got two vswitches, vswitch0 (vm network1) has one vmnic0 10.2.3.15, vswitch1 (vm network2) has vmnic2, 10,2,3,0-10,2,3,254.

I've got 3 VM's, all using VM network2, Windows 2003, Windows 2008 and Ubuntu 12.10

The ubuntu machine pang ping out, I can ping it from outside the hypervisor.  The two windows hosts cannot do either.  It is not the Windows firewall.. I've checked that its disabled but also I've got a GPO that disables that service.

With the Linux vm being able to talk to the rest of the network it makes me think it's windows VM related.. but Ill be damned if I can find it.  The latest VMtools are installed on both windows hosts too.  Their both static'd IPv4 addresses.  I tried DHCP but it failed to pull a valid address and went instead to autoconfigure 169.x.x.x

Do you only have a single network interface connected to the vSwitch ?

also why have you got two VM Networks on two different vSwitches on the same network?

This could be an Teaming Policy issue configuration issues, with the uplinked physical switch.

Also ensure that the VMXNET3 interface is in use on all VMs.

Ok I initially setup two vswitches because my uplink switch is 100mb only.  I didn't have access to a gigabit switch at the time. So I didnt want to potentially overload the only uplink.

Now, I might have my vswitches misconfigured.. but I do have servers on two different subnets here in my site so have the two vswitches will be a benefit.. but one switch per subnet will be the way to move forward.

Im still lost though as to why the linux host can communicate out/in but windows hosts cant.

I figured it out Andrew.. my uplinking switch port were not trunks and there was a vlan id mismatch between the vswitch nics and the physical switch.  I'm not familiar enough with vmware I guess.. that or the terminology confused me.

i need to craft a diagram or a flowchart regarding virtual switches to help understand them better.

I'm awarding you point anyway because you are always willing to help and I appreciate that.
