Hello -
I just recently installed Oracle VM VirtualBox 7.0.12 with extension pack. I also installed VBoxGuestAdditions_7.0.97-158510, and finally Windows.11.Pro.23H2.22631.3235.EN-US.X64 It seems to all work and I can access the internet, but not my local network.

So I have two problems I need to resolve. Please help me :)

1) The Net Work issue. I need to share files... My local network works fine on my 3 PC's so I am sure it is set up correctly on real Windows, but from the virtual machine I can not even see the network. I currently have the "EVERYONE" account set with FULL permissions on my network just for testing, but still can not see the VM from my PC or my PC from the VM. What am I missing ??

also....

2) My view inside the VM is not filling my entire screen. Full screen does work but it is not expanding the VM window to my entire monitor. If I click on full screen from the top right menu ( the little square ) it will expand to complete full screen but very low res and HUGE TEXT. Scaling is set to default 100%,

Please help me :) If you need ANY more info just ask and I will supply it.

Thank You

By default when you create the VirtualBox VM the network adapter is attached to NAT which gives internet access only.

When you first create a virtual machine, Oracle VM VirtualBox by default enables one virtual network card and selects the Network Address Translation (NAT) mode for it. This way the guest can connect to the outside world using the host's networking and the outside world can connect to services on the guest which you choose to make visible outside of the virtual machine.

This default setup is good for the majority of Oracle VM VirtualBox users. However, Oracle VM VirtualBox is extremely flexible in how it can virtualize networking.

If you want to access shares on the Host or other PCs on your network you need to change this to Bridged Adapter.

Currently I'm stuck with a desktop of 1024x768 which I cannot change. That's because my W11 VirtualBox VM is using the Microsoft Basic Display Adapter. I've not (yet) found out how to (or even if I can) change that.

Edit: even with Guest Additions installed I cannot go higher than 1024x768.
