There's a kb article for this issue. Which 4.1 Update version are you using?
"Prior to vSphere 4.1 Update 2, disabling Remote Tech Support Mode (SSH) and Local Tech Support Mode is the only way to prevent this warning from appearing. In vSphere 4.1 Update 2, you can disable the Remote Tech Support Mode Remote (SSH) and Local Tech Support Mode warnings from appearing on the hosts."
