You may be able to get around this error if your computer is running Kaspersky: Go into the web-protection section of Kaspersky and explicitly trust the following URLs.


Error Message: "The display protocol for this desktop is currently not available. Please contact your system administrator."

This message indicates something is wrong with the Virtual Machine you are trying to connect to. Often the problem will resolve itself within half an hour, but if it doesn't, you can try downloading and installing the most recent version of the client (see Installing the Virtual Lab for download instructions). If neither of these solutions fixes the problem, please submit a ticket reporting the steps you have taken.

Problem: Your Computer Display is black when you launch the Virtual Lab.

VMware only supports screen resolutions up to 2560 X 1440. This is not likely to affect Mac users. PC users should check their system display settings in Control Panel and choose a resolution below 2560 X 1440.

Problem: Your Mac Display is white when you launch the Virtual Lab.

This problem is fixed by reinstalling the latest version of the Virtual Lab. See Installing the Virtual Lab for download instructions.

If your problem remains unresolved, please submit a Help ticket to the Support Team.
