Hi,
We have a Windows 2012 RDS environment containing 3 Session host servers. To be able to use the shadowing feature I started to upgrade them to 2012 R2. Now the Connection broker and one of the session host server is upgraded but shadowing still not working.
On the Server manager GUI I can see all the RDS sessions but all the sessions on the upgraded Session host server has a sessionid equal to 0.
From powershell the Get-RDUserSession -Connectionbroker "connectinonbroker" command gives me nearly the same result. All the sessions on the R2 server has a null value Unifiedsessionid.
All the session host servers are fully operational the users dont report me any problems but I'm not able to log off or shadow the sessions on the upgraded session host server.
Any advice would be nice.
