The default gateway is not available.

Hi folks,

Today I encountered one of the most vague problems I have ever seen.

I do have a windows server 2008 r2 as the main machine plus vmware workstation 10 installed on it.

There are three VMs running. One is win2003, win2008 r2, win2012 r2.

They were running smoothly and suddenly their networks stopped except the main server.

When I troubleshooted what it is going on I got the gateway error.

Flushed the dns, renewed the ipconfig, restarted them, reset the networks configs but nothing seems to work at all.

Here is a ping on the main server:

Windows PowerShell

C:\Users\admin>ping 110.245.197.145

there is no way out of the blues that such a thing could've happened. I've tried everything and I can't seem to find the issue here.

Any help?

Appreciated in advance.

I solved it.

For every machine, the network selection specified is Bridged.

When I opened the VMWare virtual network editor I found a couple of created connections such as VMware0, VMWare1 etc.

VMWare0 was set to be bridged and in the combobox of (Bridged to:) there were three options. Two of them are network cards, one for the public communication and one for the private communication inside the datacenter. The third choice which was selected by default was "Automatic". I changed it to stick with the public network card and went back to every VMs network setting and selected Custom instead of Bridged then choose VMWare0.

I think that the old default config somehow got messed up between the two cards. What are your thoughts?

I could've deleted this entire question. But I want people who are going to search about this issue to find a solution plus free points for ya guys.

Cheers,

Phil.
