I've made quite a bit of progress (after many hours) and have learned much in the process.

I now have the lab environment setup except that my VMs have no internet access. I've played around quite a bit and it seems once I use static IPs for my VMs, as instructed in the training kit, I lose internet access. However, if I use DHCP, I can access the internet from the VMs.

When using static IPs (via the netsh interface command), I notice there is no default gateway given but I'm not sure that is the issue.

I think I can press on without internet access but I think it would be preferable if it was available on each VM.

If anybody has faced these issues also and resolved them, I'd like to hear how you solved them!
