Mapped drive is disconnected after reboot

Hello,

I have a computer that runs Windows 10, I have a mapped drive to a network share, after I reboot my PC Windows Explorer display a red "X" on the icon of the mapped drive. However, if I try to access or browse the mapped drive, it reconnects quickly. It is not a big problem for me but I do have backup software running and when drive is disconnected I get an error message. What can I do to prevent my network drive from disconnecting?

Hi TeckTheKid,

A misconfiguration with the map network drive setting is possibly causing the connection issue. I would like to confirm how you mapped your network drive. You can find the steps on how to map a network drive in Windows 10 in this support article. I want to confirm if you selected the Reconnect at sign-in check box when you mapped your drive.

I will need more details if the connection issue still occurs even if the Reconnect at sign-in option is already selected. Kindly verify the following information:

  • When did the issue start?
  • Are you getting any error messages?
  • Have you installed the latest updates for Windows 10?
  • Can you tell me the current OS Build of your Windows 10 system? Click the Start button, type About your PC, press Enter, and then scroll down to Windows specifications to find this information.

We're looking forward to your reply.

Hi all,

I was also experiencing the same issue. The drives open when double-clicked using File Explorer, but by this time most of the applications requiring network storage access have determined the location is not available.

After checking the event log I determined that my network adapter was disconnecting to renegotiate network to 1Gb. This is great for throughput but it was taking my network offline for 4 seconds (see below details from the event log).

I then checked my network adapter settings in Device Manager. After a few attempts, I changed "Set for Link" setting to on which changed the network card auto-negotiation behavior. 

Your network adapter may not be Intel but the solution should be similar.

Hope this helps.

I've got the same issue which occurred after the 1809 update. I also have KB4464330.

Mapped drives I have personally mapped are disconnected after every sign in, and yes the 'Reconnect at sign-in' box is checked. I have to click on each drive in Windows Explorer, at which point they become available again.

Mapped drives propagated by our AD reconnect without incident.
