无法让 Windows 优先考虑特定网络适配器

我们有一台带有 3 个网络适配器（2 个物理适配器和 1 个虚拟适配器）的 Windows 7 PC：

Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix  . :
   IPv4 Address. . . . . . . . . . . : 192.168.75.20
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.75.1

Unknown adapter Local Area Connection 3:

   Connection-specific DNS Suffix  . :
   IPv4 Address. . . . . . . . . . . : 10.8.0.3
   Subnet Mask . . . . . . . . . . . : 255.255.0.0
   Default Gateway . . . . . . . . . :

Ethernet adapter Local Area Connection 2:

   Connection-specific DNS Suffix  . :
   IPv4 Address. . . . . . . . . . . : 192.168.1.253
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   IPv4 Address. . . . . . . . . . . : 192.168.150.2
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   IPv4 Address. . . . . . . . . . . : 192.168.255.126
   Subnet Mask . . . . . . . . . . . : 255.255.252.0
   Default Gateway . . . . . . . . . :

当我禁用Local Area Connection 3虚拟适配器时，我能够远程桌面连接到公司网络上 IP 地址为 172.27.117.78 的另一台计算机。但如果Local Area Connection 3启用了适配器，则远程桌面无法连接到 172.27.117.78。显然，Windows 尝试连接到 172.27.117.78，Local Area Connection 3但无法访问该计算机。

因此我尝试让 Windows 优先使用适配器Local Area Connection，并使用答案这里：

  • 我设置Local Area Connection属性> TCP / IPv4属性>高级>接口度量= 1
  • 我设置Local Area Connection 2属性> TCP / IPv4属性>高级>接口度量= 2
  • 我设置Local Area Connection 3属性> TCP / IPv4属性>高级>接口度量= 3
  • 我转到控制面板 > 网络和 Internet > 网络连接 > 高级 > 高级设置 > 适配器和绑定，然后移至Local Area Connection列表顶部、Local Area Connection 2其下方、再Local Area Connection 3其下方。

Local Area Connection 3完成所有操作后，如果启用了适配器，远程桌面仍然无法连接到 172.27.117.78 。

另外，我尝试禁用Local Area Connection 2它以将其从方程式中删除。同样的问题，当Local Area Connection 3禁用时，远程桌面连接有效，但当Local Area Connection 3启用时，远程桌面连接失败。

编辑：这是输出route print（“82579LM”接口是Local Area Connection，“TAP-Windows Adapter V9”接口是Local Area Connection3）：
