Hi I connect to a remote machine C from Machine B which is connected from Machine A, How can I send ctrl+alt+end to remote machine C ? Please note I cannot access m/c C from m/c A, I need to go through B to access C. Your help is appreciated.

m/c A --> Remote destktop to m/c B --> remote desktop con m/c C.
