networking - Windows Server 2012 - No communication to other subnets

I have a bit of a weird issue. I have a HyperV server (192.168.0.3) that hosts all my VM's in my network and, up until today, I have had no issues with it.

Now for some reason the PC that is hosting the VM's can not communicate outside of its own subnet....

All other machines on the subnet have no issues, and all the VM's function fine.

There is a central router that handles all my cross subnet routing and internet routing (192.168.*.10 on all subnets). Both the router and the HyperV machine work on the same switch.

My VM's run on both my workstation VLAN/SUBNET (192.168.0.0/24) and on a VM only subnets (192.168.100.0/24 192.168.101/24)

There has been no power or internet loss at the location that hosts the server hardware, the HyperV server simply stopped communicating with anything outside the 192.168.0.0/24 subnet.

A tracert to my RAS server stops at the router (192.168.0.10) and goes no further, all pings to and from any other subnets just time out.
