Interoperability of RGS and Microsoft Remote
Desktop Connection
This section discusses interoperability considerations for RGS and Remote Desktop Connection (RDC).
Because RGS and RDC both provide connection to a remote desktop, their interoperation is important
to understand.
If a local user is connected to a Remote Computer using RDC, and then attempts to establish an RGS
connection, the RGS connection only works if the local user credentials match for both connections. This
implies that the same user wants access to transition from RDC to an RGS connection. If the credentials
match, the current RDC session disconnects, and the RGS Receiver takes control of the Remote
Computer Windows desktop session. The current user does not log off, and work continues with the
new connection.
The reverse works as well. If a user is connected with RGS, and then connects with RDC (using the
same credentials as the RGS connection), the RDC session displaces the RGS connection. In this case,
the RGS Sender will disconnect all Receivers (including all RGS collaborators). The Windows desktop
session remains active during the switch.
If an RDC user disconnects from a Remote Computer using the RDC disconnect button, the session
remains logged in, and all applications continue to run. The session, however, locks its screen. An RGS
connection works only if the credentials match the currently logged-in user.
If a user logs out of their session while using RDC, the RGS Sender returns the system to its initial
logged out state. Any authorized user can connect and log into this system using RGS.
An RDC connection made to a Sender already occupied with a RGS connection by a non-matching
user prompts the new user to logout the current RGS user. Only administrators can log out other users.
Non-administrators are refused with a warning message about permissions. If RDC logs out the current
RGS user, then the Sender disconnects all of its receivers (including all RGS collaborators).
Under reverse circumstances for the above, RGS connections will not log out an existing RDC user,
regardless of authority. RGS will report an authorization failure message concerning a different user
owning the desktop
When RGS displaces an existing RDC session on Windows 7, the desktop may enter into a temporary
logged in and unlocked state due to these operations. The user should exercise caution in situations
where even a temporarily unlocked desktop is a security concern.
Cause Solution
Windows 7 performs session operations that are outside the
control of RGS.
This issue can be avoided by logging out of the RDC session
before establishing an RGS connection.
Remote Computer power saving states
In order for a Local Computer to establish connection to a Remote Computer, the Remote Computer
cannot be in a power saving state, such as Windows hibernate or standby. Furthermore, the Remote
Computer cannot utilize wake-on-LAN in an attempt to power-up in order to respond to a connection
