We recently deployed out serveral servers all running server 2012 at various clients. They are all mostly Dell R410's or Dell R520's.
We have noticed that the RDC connections to these servers are far slower than the connections to our 2003 and 2008 servers that run on the same networks.
We have tried to add the following registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters as mentioned in other support articles but our connection is still slow.
Has anyone else foudn this sort of issue with server 2012 RDP.
