Error connecting to server conosle in vSphere client
Description – When connecting to a server’s console you receive an error that says, “Unable to connect to the MKS: Failed to connect to server esxi01.laptoplab.net:902”
Cause – This is due to a DNS problem where the computer connecting to the console cannot resolve the name for the ESXi hosts. This is likely to happen in a lab environment. If this is happening in a production environment then you need to troubleshoot why you cannot resolve the names for your ESXi hosts. May be a sign of a bigger problem.
Solution/Workaround – Create HOSTS file entries for the ESXi hosts management IPs.
