When in Cisco Packet Tracer, the CLI for PCs is not available, nor does it allow me to enter configuration commands for a lab. The Prompt never matches "PC1>" etc.; it's always "C:\>" I can execute ping but never can launch the command prompt from the desktop modes. Conversely, routers seem to operate and I can launch the IOS command line interface and configure away. Is there a setting in PC Matic capable of blocking the PC's CLI page?
