That message is very much a message one would get on a network where the Info Tech Security Manager has resricted LAN ports, probably at a switch, to specific users. 

So where are you at?

Thank you.

The Error message you are getting seems to be self explanatory. You are trying to run Lr (what exact versions I don't know as you haven't stated) on a computer that does not match the IP range of the LAB your are assigned to and able to use that program in and on what computer you are supposed to be using.

This is an IT issue for your organization. you need to contact them.
