Can't map network drive on Windows 7 after closing VPN connection

  • 772

So the command below works if I reboot my computer. But whenever I VPN to a certain customer's network on Windows 7, I lose my mapped drive. And when I try to re-establish the mapped drive (even after closing the VPN connection), I get this error at the Windows command prompt. FYI: I have another Virtual Machine running Windows XP and this never happens on there.

C:\Windows\system32>net use z: \\{my company domain name}.local\dfsroot\docs
System error 53 has occurred.

The network path was not found.

For this question, I'd just like to map this drive without having to reboot Windows 7. How can I do that?

Bonus questions: Why does this only happen on Windows 7? How can I keep my VPN open and also map this drive? Are there tools for troubleshooting these types of things?

So I'm no networking guru, but I see 1 difference with the ipconfig /all command. The Physical Address is different and that's it. And the Lease Obtained and Lease Expires, but those are probably irrelevant. If there's any other info you need, please let me know.

    I'm just taking a shot in the dark here, but have you tried running the following after closing your VPN connection?

    ipconfig /release
ipconfig /renew

    and possibly followed up with

    ipconfig /flushdns
