因此，如果我重新启动计算机，下面的命令就会起作用。但是，每当我在 Windows 7 上通过 VPN 连接到某个客户的网络时，我都会丢失映射驱动器。当我尝试重新建立映射驱动器时（即使在关闭 VPN 连接后），我在 Windows 命令提示符下收到此错误。仅供参考：我有另一台运行 Windows XP 的虚拟机，这种情况从未发生过。
C:\Windows\system32>net use z: \\{my company domain name}.local\dfsroot\docs
System error 53 has occurred.
The network path was not found.
对于这个问题，我只想映射这个驱动器而不必重新启动 Windows 7。我该怎么做？
附加问题：为什么这种情况只发生在 Windows 7 上？我如何保持 VPN 处于打开状态并映射此驱动器？是否有工具可以解决此类问题？
我不是网络专家，但我看到 ipconfig /all 命令有一个不同之处。物理地址不同，仅此而已。还有租约获得时间和租约到期时间，但这些可能无关紧要。如果您需要任何其他信息，请告诉我。

我只是在这里尝试一下，但是您是否尝试过在关闭 VPN 连接后运行以下命令？
ipconfig /release
ipconfig /renew
并可能跟进
ipconfig /flushdns
