Tricerat ScrewDrivers and Simplify Scanning products use the virtual channel architecture to communicate between client and server endpoints. Our products, technically called client plugins, support Microsoft Remote Desktop Protocol (RDP), Citrix Independent Computing Architecture protocol (ICA) and the VMware PC-over-IP protocol (PCoIP). This article is specific to Microsoft's Remote Desktop Protocol (RDP) only. |
Starting with Windows Server 2012, Microsoft introduced a new feature to their Remote Desktop Protocol (RDP): Dynamic Virtual Channels (DVC). Previous RDP implementations are now known as Static Virtual Channels (SVC).
Several versions of Tricerat products support SVC and DVC. Starting with version 6.1.1 we modified our support for DVC based on Microsoft's increased emphasis on DVC usage over SVC. These modifications were specifically targeted at Windows Server 2012 and above. On these operating systems, Tricerat will not attempt a SVC connection due to incompatibilities with DVC usage. Even one attempt of a SVC connection can prevent a future DVC connection from working properly. Once DVC connections are broken only a server reboot will correct the issue.
