v19.30.5.21 での更新項目

機能

• Added RDP File Signing Mechanism:
  • Remote Access v19.30.5.21 embed Connection Client V127 which now sign RDP file used to start the connection to your server, whether from a .connect file, or by selecting the “remoteapp“ display mode from your Remote Access web portal.
  • This RDP signing mechanism has been added to comply with Microsoft new security policy regarding un-signed RDP usage.
  • However, simply signing the RDP file to be used is not enough to remove these warnings, as you will also need to:
    • Install the new RDP signing certificate in the "Trusted Root Certification Authorities" store.
    • Register the thumbprint of the certificate as a trusted .rdp publisher (this requires you to be an admin).
  • Both actions are done by the Connection Client setup via the following new page, when clicking on the “Configure now (requires admin)“ button.
  • This configuration only needs to be done once.
  • You won’t be asked to install the certificate next time you install the Connection Client, unless TSplus has renewed their RDP signing certificate, which should be every 5 years.
  • Important:
    • The RDP signing certificate installation page does not appear when you install the connection client "for all users" since this mode starts the setup as an admin, making TSplus able to automatically install and register the certificate without needing to ask the user to elevate as an admin.
    • The .rdp file signing processing, done the first time a new .connect is launched, is done remotely by the licenseapi.dl-files.com server.
    • The certificate itself is also being downloaded by the setup connectionclient.
