I don't think that this is appropriate. I am also a Network Admin and all personal computers even smart phones are not allowed to be connected to our network.
This is also my personal laptop that I connect to their network and then bring home each night.
Strange response from your IT Dept.
When I asked by IT Department about this they simply said to "be creative". This policy blocks any program that runs of a CD, installer or general program.
I don't think that we can help you with your request or bypassing network policies.
