Windows 10: Lost connectivity to NAS drives as mapped drives

I can no longer access NAS devices. I have 2 NAS: Synology DS420+ and WDEX4100, that I have been using for several years, mapped to Y and Z respectively. A couple days ago, I lost connectivity.

The available shares will be listed there. Then Try to List the content of one of the directories: Code:

This should list the content of the directory, If all this works Try to map a drive on one share: Code:

Pls reply with the "response" of the first "encounter" of a non positive output. This exercise should reveal if you have a Network or Protocol or Cipher or Authentication problem.

@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 ?
