How to Enable/Disable Multiple RDP Sessions in Windows 2012 R2

How could i enable multiple sessions in Windows 2012 R2 session host server? When there is more than one collection available for a user i got this error and i think it is beacuse there is some standard restriction that only one session for a user, but where and how do i change this? The deployment has connection broker server, gateway server, rdweb access server and some session host servers.

Hello my friend,

You need to perform this on the RDP server or on all your RPD server and that's all. Yes, it's normal that the admin do not have a problem :)

Thanks

Hi

By default, Windows 2012 servers allow a single Remote Desktop session. If only one session is available and you take over another person's live session, you may choose to enable multiple RDP sessions. This article describes the process for enabling and disabling multiple sessions.

Enable Multiple RDP Sessions

   -  Log into the server using Remote Desktop.
   - Open the start screen (press the Windows key) and type gpedit.msc and open it
   - Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.
   - Set Restrict Remote Desktop Services user to a single Remote Desktop Services session to Disabled.
   - Double click Limit number of connections and set the RD Maximum Connections allowed to 999999.

 Disable Multiple RDP Sessions

   -  Log into the server using Remote Desktop.
   -  Open the start menu and type 'gpedit.msc' and open it
   - Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.
   - Set Restrict Remote Desktop Services user to a single Remote Desktop Services session to Enabled.

Let me know if this solve your issue.

Thanks

so its true that i have to do this from group policy? In 2008 there is a checkbox in configuration page. If i have 15 session host serveres, what group policy would i change on the domain controller to do this once?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

should this be done on the connection broker? each user have only one connection to each session server. the problem is if there is 2 or more collections that a user have access to. The Administrator dont have the problem.

yes, its like Exchange 2013, the interface is simple and slow, why are they doing this? It looks nice, but i want function and not some fancy slow simple interface. Its like they want us to like slow fancy interface so its easier to use there slow cloud stuff like Office365 etc.
