All, since upgrading out internal infrastructure to vSphere 4.1 we have not been able to connect to the guest vm console from either vCenter or direct to ESX using the vSphere 4.1 client. This was working in vSphere 4.0.
The error returned is "the hostname could not be resolved".
A network trace indicates that although the initial connection to vCenter or the Host is successful (DNS resolves) the connection made within the application to the console fails as a dns call is made to the external dns server ignoring with windows dns resolution order!
Has something changed in the vSphere 4.1 client?
We have enabled IPv6 on the host and registered the AAAA record in DNS bit no improvement. Anyone else seen this?
