Issue: After upgrading Lab Manager to 4.0.3, clients are not able to view the console. It is a black box and the console is not able to be seen in Internet Explorer.
Reason: IE uses an ActiveX plugin that is will not work with 4.0.3 or possibly the new VI client. It will not prompt to be reinstalled or updated.
Fix: Update the Lab Manger IE Plugin.
