I want to setup a windows server computer.

I have the same problem on all windows server editions since 10 years: If 2 users try to connect with RDP, the first user is disconnected.

What i want to do is to allow 2 users at the same time.

I have read i need to buy cals for my server.

But i want to create a virtual machine on azure portal. Is there a way to do this on azure ? Or should i buy CAL directly to a Microsoft Reseller ?


  • You need to use different users for each person logging in. – Mark Henderson Sep 15 at 21:41
  • I do not need CAL licences ? – Bob5421 Sep 16 at 7:24
  • No you don't as long as we are only talking about one user requiring two concurrent sessions – Matthias Güntert Sep 16 at 8:35

In the registry try changing the value of HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ TerminalServer\fSingleSessionPerUser from 1 to 0. If that key doesn't exist add a new DWORD accordingly.
