I am running ESXi 4.1, VM's have been safely running for 2+ years now. Issue arose today where 1 of the VM's couldn't hit the internet anymore. When I try to change setting inside OS on the connection, I get 'an unexpected error occurred' pop up. All other VM's are fine, I removed/added back the adapter with no change.
Not sure where to start trouble shooting this but need a fix fast as this is a prod box.
Thank you,
Mike
