Re: An error occurred while opening a virtual disk. Verify that the converter server and the running source machines have a network access to the source and destination ESX/ESXi hosts

I got the same result, but I'm sure it is something to do with firewall or routing.

I will take it with our network guys, and hope they can help me:)

Because I can't see that this is anything to do with VMware

Thanks for all your help
