摘要

远程桌面会话主机（RD 会话主机）的活动用户会话数超出正常操作条件。

原因

RD 会话主机服务器上的活动用户会话总数接近安装了 RD 会话主机角色服务的计算机硬件的性能限制。

解决方案

为预防这种问题，根据安装了 RD 会话主机角色服务的计算机硬件的性能限制配置允许的最大Active Sessions数。

要配置此 RD 会话主机服务器允许的最大Active Sessions数，请在“远程桌面会话主机配置”中“连接属性”对话框的“会话”选项卡上配置“Active Sessions限制”设置。

也可以通过使用组策略控制台来控制上面提到的设置。在导航窗格中，依次打开“计算机配置”、“管理模板”、“Windows 组件”、“Remote Desktop Services”和“会话”。根据需要更改允许的最大Active Sessions数的属性。
