xenstore-ls (vif part only) shows:

For the working FreeBSD guest:

 vif = ""
     0 = ""
      backend = "/local/domain/0/backend/vif/35/0"

      state = "1"
      handle = "0"
      mac = "00:16:3e:04:a5:87"

For the Windows Guest:

      backend = "/local/domain/0/backend/vif/1/0"
      backend-id = "0"
      state = "4"
