Virtual Desktop Service downtime - Thursday 22 October

Posted on 13 October 2020

The Virtual Desktop Service will be unavailable whilst we perform an upgrade. You may need to upgrade the Parallels Client software on your device once this work is complete.

On Thursday 22 October, we'll be upgrading the Virtual Desktop Service ( The work will begin at 7am, and the VDS will be unavailable for around 30 minutes. Any users that are signed in will be disconnected, but once the service is restarted they will be able to continue their session where they left off.

After this upgrade, any old versions of the Parallels Client (the software on your device that you use to connect to the VDS) will no longer work and will need to be updated. If your client is out of date you will see the message below when you attempt to connect to the VDS:

“Code [01/00000030]

A security rule prohibits access for this version of Parallels Client.

Upgrade [to the latest version of] Parallels Client to ensure you meet requirements and are protected by the latest security updates.

For more information, contact your system administrator”

Managed devices

If you use a managed device (eg an office PC or managed laptop) you should already be using the latest version.

You can check this by opening the Parallels Client, going into the Help menu and clicking the About option. In the window that pops up you should see the line Security patch version 1

If you don’t see this, you can install the latest update from Software Center - you will need to connect to the VPN first if you are off campus.

Unmanaged devices

For Windows, macOS and Linux devices you will need to download and install the latest version of the client from the Parallels website.

For Android and iOS devices you need to go into the iOS App Store/Android Play Store and make sure the Parallels Client app is up to date. If it isn’t there will be an update waiting to be installed.

If you’re on the latest version you should be able to see Security patch version 1 within the app under Settings > About Parallels Client.

HTML5 Client

The HTML5 client will be unaffected by this change so you can use this as a temporary workaround if you’re having trouble connecting to the VDS after the work is complete. 

Sign in to, right click on the virtual machine you want to use (eg UniDesktop, StudentDesktop) and select Open in Parallels HTM5 Client.

We hope that the timing of this work will mean that it has minimal impact, but please contact if you have any questions.
