ESXi - VM can't access the Internet (or ping ANYTHING)

[Borvik]

I've got a difficulty on an ESXi box.

I've got a Windows Server 2003 VM running on it - and it used to work fine.

There was a power outage yesterday (that lasted longer than the UPS could handle), and now today the VM can't see the rest of the network though WS2K3 thinks it's connected to the network.

We are using VLANs to segregate our subnets, and the VM is on a separate VLAN than the host machine (this used to work).

ESXi host address: 192.168.104.21
WS2k3 VM address: 192.168.107.7

The VM can't ping the host address, or any other physical computers on the same VLAN even (the 192.168.107.* subnet).

Any ideas?

Uninstall the NIC in the 2003 instance. Then in ESXi, remove the nic from the server once it is powered down. Then reverse this order. Re-add the NIC in VM and configure it for your VLAN. Then when the machine boots up, it detect it again. Make sure the VMTools is up to date as well.

Thanks for the reply TechyMcSe2k.

I'm not sure what happened (didn't even try that), but it is now working.

I've been in contact with our network guru (who is offsite), and I think he got into one of our switches and fixed the problem.

I'm not sure what the problem was yet - though I hope to get it out of him, so I can post what happened and what the fix was.

Ok, apparently there was a change to our switch that allowed the port it was on to be on the VLAN I set it to - that wasn't saved. The power outage cleared that and when it came back up it therefore didn't work.

He re-added that port the the VLAN and saved it this time.

Thanks.
