Windows 10: File explorer slow when mapped network drives are disconnected

Hi there, there are some mapped network drives on my windows 10 pc in order to access my home NAS and other shared folders via SMB when I'm connected to my home network.

The problem is that windows file explorer is terribly slow when I'm not connected to the home network (it freezes for even 30 seconds and it's quite annoying) because it seems that file explorer tries to fetch them until a timeout occur.

Is there a way to edit this timeout value (maybe a registry entry) or, alternatively, to tell file explorer to don't check for mapped network drives every time, without having to unmap them?

I'm using Windows 10 version 1909, but even with versions 2004 and 20H2 the same problem occurs.

Thanks in advance

Disconnected network drive showing in File Explorer

Recently a strange drive appeared in File Explorer. It is labeled (A Disconnected Network Drive.

I have NEVER mapped a network drive on this computer. When I attempt to right click and disconnect I get a box saying "This network connection does not exist." If I just click on it I get a box saying it is not accessible. Access is denied. Properties
simply says it is empty.

I cannot get rid of it. Trying to delete it under Drive Mapping in Explorer yields an error message saying it does not exist.

I went to safe mode with networking. It does NOT appear in File Explorer in Safe Mode. However it continues to appear in normal mode.

It is as if Windows just made something up to clutter my File Explorer.

BTW I already tried using admin command prompt to delete it. I get an error message saying that the drive does not exist.

Someone on a forum suggested trying to map a new drive on the same drive letter. Win 10 will not even display drive A as a choice in the dropdown.

How do I get rid of this?

 

Unable to disconnect from mapped network drive

I receive the following error when I try to disconnect from a self mapped network drive: "network connection does not exist"

The network drive icon appears with a bid red x and says it is disconnected, yet I can double click on it to enter the mapped folder. Doing this does not reconnect the folder, and remains disconnected. This causes problems because programs that pointed
to this path are unable to read the files. I am unable to remap this drive because the associated drive letter (E and mapping no longer shows up in the list.

I've tried all the typical suggestions including:

--I tried to do it via the command prompt with the net use delete command, but it can't be found in there.

--Tried to above with the actual network path instead of the drive letter, did not work

--Tried to delete the registry entries from:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2

HKEY_USERS\. Default\Software\Microsoft\Windows\CurrentVersion\Explorer\Mountpoint2\

None of these solutions worked. Though deleting the registry entries momentarily hid the disconnected drive, the drive letter was still not available for mapping. I tried to force the drive letter (E to map to my optical drive, which worryingly, pointed
back to the mapped network location on the NAS instead of to the optical drive.

How do I get rid of this? Reformatting the computer is not an option.

 

Mapped Drives Issues

To clarify .... the issue is the Windows 10 OS. It is with Windows File Explorer. The Mapped drives used to appear in File Explorer's left panel list of drives and folders. Two days ago File explorer stopped show the mapped drives. so not they don;t appear in the list of Drives and folders.

I did, it has no effect. I also check the NAS devices they support SMB 2.0. Also I have several other computers on my home network they work fine with the mapped drives and They do not have SMB 1 turned on. So it is something that happened to the computer in question.
