Hi
Partition C and D without any error. I suppose the problem is caused by the TS service running as RD Connection Broler, RD Sesion Host and RD Web Access.
I removed Collections that I had prepared for users and now after restarting the server, RDC connections work.
After restart server I see one error : "Remote Desktop Services failed to join the Connection Broker on server ..." and "Remote Desktop Connection Broker Client failed to redirect the user " every RDC session
But now RDC working without black screen.
