Cannot open network drive, but I think I caused the issue

When I try to open my my router-attached network drive, I get this error:



It was working just fine before, but I think I caused the problem. I was trying to fix something else, and followed the advice in this video:


But then after I discovered the network drive error, I then went back to the video and tried to undo what he said to do. But I can't open the network drive anymore. Does anyone know what to do to fix this issue? Thank you

If you did not backup your registry changes, and do not have a system backup image , try system restore to a point earlier than when you made the changes..

A bit of advice if you care to take it...always CYA when working in the registry or running scripts. Likewise, NEVER make such changes unless you know for sure they come from a reputable source....like @Brink tutorial section. Not only does he give fixes, he also gives a method to undo the changes if necessary.
While there are some knowledgeable youtube videos, be cautious because the so-called experts are a dime a dozen. You can not trust them all.

I use system images for my insurance. I've screwed up before or I was given bad advise so it's saved my bacon more than once. If I work in the registry, I always export any change I make so I can undo it.

I did actually image the hard drive after I got all my programs installed using clonezilla and redo rescue. So I do have that option to go back. It just seems like such an error would be fixable without having to resort to that?

Yes, I will not follow anymore questionable YouTube videos from Indian guys..

Did you try system restore?
