I have just swapped my motherboard, CPU and memory.

 

I have kept the same Intel NIC

 

Since swapping the hardware everytime i start my windows VM i lose network access to the unraid Host

update: seems a bit random, sometimes doing it before starting the array etc

 

I have verified this several times booting into GUI mode

 

Any help would be greatly appreciated

 

I have deleted both my network config file and the vfio-bind config file

Just the Windows VM, or others as well?

Sorry if i wasn't clear , the unraid Host

There's this constant issue with the NIC, later resulting in a hang:

Try installing the NIC in a different PCIe slot if available.

Thanks for taking a look. I've concluded the NIC has been damaged somehow in the changeover.  Rolled up a trial version of unraid on a fresh USB and had the same issue. Have switched over to the onboard NIC and all seems to be fine
