I receive the following error when I try to create a console session to one the virtual machines from vCenter

"Unable to connect to the MKS: Permission to perform the operation was denied."

If I log into the host directly and do not have this error and am able to create the console session.

Have you tried a different vCenter user account ?

when you say logged into host, what server is this vCenter Server ?

A different vCenter user account provides the same error.

I can log into the single host ESX server(192.168.50.5) directly through the vSphere client then create a console session to the vm on the host without error.  If I log into vCenter(192.168.50.100) then access the vm on the host ESX server I receive the error.

When you login to the host, you will be using root credentials.

when you login to vCenter Server, you will be using user credentials which have been defined by vCenter Server, and the Role may have permissions to stop you looking at the console.

Did you setup the roles and permissions?

Are you logged in with the Super User - Administrator Account via vCenter Server...

All other vm's in vCenter are ok.  The vm that is having this problem does not have VM tools installed.  Could this be the reason?

Nobody has changed permissions on this VM?

It's always recommended to install VMware Tools on all VMs, but you should still be able to obtain a console.

I would remove from the inventory, and re-add to the inventory.

If the VM is off, do you still get a permission issue?

No permissions have been changed.  I will schedule some time this weekend so I can remove the vm from inventory and identify if the issue exists if the vm is off.
