Sandeep,
I don't have another system that I can try. I do know that if I disconnect from the E-Plus the onboard ethernet connection works fine - I tried it today. And all other laptop ports are working fine connected or not.
I'll hopefully get a screen shot today with the replicator connected and disconnected, but I'm not sure what I should be looking for. I'm looking at the Device Manager right now with the laptop connected to the replicator and don't see anything in there that looks like the replicator. It does tell me that the Intel(R)82579LM Gigabit Network Connection "is working properly".
