远程桌面RDP升级8.0后（补丁KB2592687）连接被拒绝问题的解决

打补丁：KB2592687，更新系统RDP协议至8.0版本 之后，重启系统之前正常，重启之后突然无法远程桌面访问，提示：连接被拒绝，****（意思是用户未被授权访问） 原因是RDP升级后安全审核加强，以前不在“Remote Desktop Users”组里面的用户，只要系统属性-远程设置里面被允许就可以了，但现在访问用户不仅要在系统属性-远程设置里面被允许，而且要被添加至 计算机管理-用户和组里面的“Remote Desktop Users”组里 才可以，添加至该组之后，原用户正常访问。 参考：https://technet.microsoft.com/en-us/library/ff817585(v=ws.10).aspx The following error message appeared after I install the virtual GPU: “Connection was denied because the user account is not authorized for remote log on.” All users (even users who are part of the Administrators group on the virtual machine) who need to log on to a virtual desktop that has a RemoteFX 3D Video Adapter need to be members of the Remote Desktop Users group. 另外注意一下防火墙（与此问题无关）： I am unable to connect to the RemoteFX virtual desktop. Connection is denied even though Remote Desktop access is enabled. A new Windows Firewall rule is added for RemoteFX. If you perform a new installation and enable Remote Desktop by using the System properties sheet, the rule is enabled automatically. You must enable the RemoteFX Windows Firewall rule manually if you do either of the following: Enable Remote Desktop by using the netsh command or the Windows Firewall APIs. Upgrade to Windows 7 with SP1 on a virtual desktop that already had Remote Desktop enabled.
