My understanding is that GatewayPorts should not be necessary.
Does it still work if you set it back to 'no'?

That would indicate some problem with the guest registry.

You could grab it and post it somewhere (but note that registries
contain sensitive data such as passwords):

  mkdir /tmp/registry
  virt-copy-out -a /path/to/guest.img 'win:C:\windows\system32\config' /tmp/registry

(I only need to see the files 'SYSTEM' and 'SOFTWARE')
