<p>When you need to grant RDP access to a server for non-admin users you will add those users to the Remote Desktop Operators group. If you&#8217;re trying to do that on a XenApp server, you will receive the following error message:</p>
<p>Connection Error</p>
<p>The desktop you are trying to open is currently available only to administrators. Contact your administrator to confirm that the correct settings are in place for your client connection.</p>

<p>The problem is that ICA_TCP protocol is not allowing RDP connections to XenApp servers if you&#8217;re not a member of administrators group.</p>
<p>To fix this issue go to:</p>
<p><strong>Control Panel | Administrative Tools | Terminal Services | Terminal Services Configuration</strong></p>
<p>In the middle pane double click on the ICA-TCP connection and select the <strong>ICA Settings</strong> tab</p>
<p>Deselect the <strong>Non-administrators only launch published applications</strong> option under Initial Program part.</p>

<p>Hope this helps. If this solution still hasn&#8217;t solved your issue, please leave a comment below.</p>
