Cannot map drives

HI All, i have 1 pc that i cannot map my pr2100 to. i have 2 other pc’s that can map just fine. its very frustrating. never touch the homegroups so they are at default settings. i made sure that the drives are in the windows credentials. i’m out of ideas on what to do. I’ve also done the regedit setting but to no avail. sorry i just saw i posted this in the wrong section.

I find that using WD access to open or start the web settings does almost all I need.

A few older version of the backup program Acronis did need the map feature.

WD access is working on my windows 7 and 10.

I have seen the same problem but nevel really looking into way some of my many systems do that.
