If there are errors with SFT (or any other feature) there should be 1 or more dwmrcs entries in the Application Event log on the remote machine. Please copy and paste the full text of each of those entries and send this information to our support team at Support@dameware.com so we can review it. Please also send another screen shot of the exact error that's displayed when you try to open the SFT drop window on the remote machine (Shift + blue folder).
DRS also provides you with several direct system tools and TCP utilities, allowing you to remotely troubleshoot without having to launch a full remote session. This helps keep productivity disruptions to a minimum while the problem is resolved. 2b1af7f3a8
