What do the PC configs look like?

Could you paste screenshots?

Also, what does the switch config look like for the ports connected to the PCs and the uplink?

interface when portfast is enabled, can cause temporary bridging loops.

Use with CAUTION

 

%Portfast will be configured in 2 interfaces due to the range command

but will only have effect when the interfaces are in a non-trunking mode.

PC 2 has the wrong IP adddress and is in the wrong subnet. It should be 192.168.4.4, not 192.168.3.4.
