A client was logging into Small Business Server Remote Web Workplace , however upon initializing the RDP connection with the server. The user was not utilising the full screen size of his local machine and there where black lines surrounding the RDP border. This is usually an issue with resolution set on the initial web settings. After checking this on clicking Optional Settings before clicking on the selected client computer, this was set to full screen.  The RWW takes these settings on launch and saves them to a Default.rdp file on the local My Documents folder so future connections can utilise these. I checked this file and the resolution had been set to full screen. Upon launching the rdp file and putting in a test Remote Server , the screen opened up to the correct resolution. The issue was the user had increased the zoom size of Internet Explorer to %125. This means when the RDP client tried to initiate the screen size through internet explorer it had the wrong resolution. Changing this back to 100% ( Toolbar – View , Zoom ) fixed the problem.
