Windows 10: SMB Network Error 0x8007003B while coping small file using mapped NAS drives

I try to copy SMB small txt file from one location to the other one on the same NAS drive using mapped drive on Windows 11 22H2.So, let's say I have mapped drive X:\XFolder on NAS and second mapped drive on the same NAS Y:\YFolder, two different folders on the same NAS drive. I do simple file XYFile.txt copy operation from X:\XFolder to Y:\YFolder, the Windows File Explorer displays message like this "network error 0x8007003B"... What ? The result of this operation is corrupted XYFile.txt in destination folder Y:\YFolder.If I do the same similar file XYFile.txt copy operation using Windows

Connecting NAS - mapping of drives

@sygnus21,

Yes of course, but I when directly to the NAS manual and OP Specific machine will never support anything else....

That is mostly why I suggested FTP instead of SMB, to avoid having to install SMB1.

Are you able to map your drives now ?

 

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.

 

File transfer error and lag 0x8007003B


Hi !

I am having problems with file transfers from my PC to my NAS. I do not have this problem transferring files from a drive on my pc to another drive on my pc, only to the NAS. I am getting some serious lag with small files and error's with big files.

If I try to transfer a small file, the transfer window appears but it takes a couple of seconds to start (maybe 10 seconds or so).

If I try to transfer a large file (a couple of Gb's), the transfer window appears but I get an error (0x8007003B) and the transfer fails.





Now, this is what I tried to fix the problem ;

- Disabled Fire wall
- Disabled Anti Virus
- Uninstalled Anti Virus
- Reverted to an older Firmware on my router
- Reverted to an older firmware on my NAS (QNAP 469 Pro)
- Disabled the Teredo adapter (netsh interface teredo set state disabled)

I am all out of ideas.... This problem just came out of no where, not firmware update was done on the router or the NAS when the problem appeared.


Any help would be appreciated

Thanks
