@wirestyle22 please confirm the subnet mask and DNS on the VMHost in questions.
Subnet Mask is 255.255.255.0 DNS is set to the DC that is inaccessible (primary) with the secondary set to the DC that is on but not working correctly (Secondary).
This host DNS is set to using the VM that is offline.
The fact that this VM is offline is the cause of the DNS related issues he's having.
Just stop cluttering the thread. We are resolving a down VM not DNS. We realize there are DNS issues from bad configuration. but nothing currently being worked on has a damned thing to do with that.
Fair enough, I was looking at the problem of him not being able to access the host from vsphere.
But it's a trivial issue.
DNS has nothing to do with it. He was connecting by IP. 192.168.10.12. DNS is not required for that. only a subnet.

JB - could WS be denied direct access to the ESXi host because he's running vSphere Web client (you know the control setup vmware has for multiple VM hosts?)

@JaredBusch said in Domain Controller Down (VM):
Alright @wirestyle22
from the VMHost, there is a network diag section. shouold let you input things to ping.Can you ping the gateway?
Can you ping any other device on the LANFailed pinging to the gateway.
Succeeded in pinging the 2008 DC -

he's not trying to connect to vsphere via a hostname though, he's trying to use an IP address.

Succeeded in pinging the 2008 DCThat is a problem.

log into the 2008 DC and look at it's IP settings and share them if possible.

he's not trying to connect to vsphere via a hostname though, he's trying to use an IP address.
He was also using the wrong IP address. In either case it means that there is nothing wrong with the equipment between the hypervisor and his workstation (or the rest of the network).
I think I read this already, but is it not possible to restore a backup of this VM. (are there none?)
-
can you log into the vSphere web console?

None known. At this point we are simply trying to get the VMDK to recreate the VM

No
What is the IP of that?
is the ESXi server with the down VM on it 192.168.10.14?
I'm trying to keep that stuff straight as I help. -
@JaredBusch tested again just to see and the first ping test resolved the hostname the second didn't. unsure if that is relevant

How are you trying to access the Web console, via IP in a web browser or by a URL?

I did not think ping doe not resolved hostname on ESXi. What exactly are you doing?

There is a network test in ESXi that pings 3 IP addresses. 1 is the gateway. 2 is the 2003 DC which isnt on, 3 is the 2008 DC and 4 is the hostname. the 2008 DC is the only successful now although the first test the hostname did resolve. It has not since.

You're having DNS issues, so it's expected that DNS would fail eventually.
How are you trying to access the Web Console?
Are you using
https://SERVER-NAME:9443/vsphere-client/orhttps://ip address:9443/vsphere-client/ -
Not being able to ping the gateway means it sounds like something was restricted on the management network.
Since your 2003 DC is down, give your workstation the IP of the DC and try to connect with the thick client.
