The remote session was disconnected because there are no Remote Desktop License Servers available to provide a license

The following typically resolves the error: The remote session was disconnected because there are no Remote Desktop License Servers available to provide a license while trying to connect to a server from a remote computer.

1. If you have RDS deployment, did you create a session collection and make your RDSH server part of the collection?

2. In Server Manager -- RDS -- Overview -- Deployment Overview -- Tasks -- Edit Deployment Properties -- RD Licensing tab, did you set the Licensing mode and add the FQDN of your RD Licensing server?

3. If this is a standalone RDSH server (i.e. you didn't create an RDS deployment via Add roles and features), did you configure the licensing mode and licensing server name using group policy?  For example, you could use gpedit.msc and configure the below settings:

Computer Configuration\ Administrative Templates\ Windows Components\ Remote Desktop Services\ Remote Desktop Session Host\ Licensing

Use the specified Remote Desktop license server     Enabled

Set the Remote Desktop licensing mode     Enabled

4.  Restart the Remote Desktop services by typing Services.msc from the "Run" command.

Windows 7 and Server 2008 R2 updates KB4480970 and KB4480960 causing network issues

The issue is triggered only if the user attempting to make the connection is an administrator on the machine that hosts the Share. If the user is "just" a user on the device that hosts the share, the connection should be fine.

A workaround has been published to address the issue. It modifies the Windows Registry and should be run on the system that hosts the share. Note that you need to run from an elevated command prompt.

• reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f
• Reboot the PC.
