Windows 10 pro using Win Xp in Hyper-v connecting to LAN problem

Hi Guys,
Im new to the Windows 10 world, I am working with a small company with very outdated software...and hardware for that matter.
I am trying to upgrade a PC to a new Desktop running windows 10 pro, that was the easy part. All the other old systems are running Windows XP and are connected to a central computer running Windows 2003 server. The software we use wont run on windows 10 so I am using Hyper V on the Windows 10 PC to emulate XP to connect to the server and be able to use the software for the business.

I have a Hyper-V XP set up and have been able to add the network adaptor (Realtek PCIe GBE Family Controller) through the virtual switch manager, but can not get it to show up.

Hyper V aside I can not see the network I am trying to connect to from the regular Win 10 drives and devices list either, I am assuming it is because Server 2003 can not see Win 10, but I have been fooled before.

So I am running out of ideas on how to solve this without re inventing the wheel, any suggestions would be great, hoping there is a simple solution that I have not banged my head against the wall lon enough to notice.
Thanks in advance

Will give that a go
