Metasploit Exploit Network

I am trying to exploit a computer on my school network for computersciences. The payload I created with Veil-Evasion worked with a friend of mine who was on another network. However on the schoolnetwork it didn't work. We believed this might have something to do with a server firewall. My question to you is if the problem will be solved when we connect the host to the LAN?

Will my computer have enough rights when I connect to the LAN?
