Can't access OMV server through windows

So yesterday I finally was able to get the OMV server up after fighting a war against my WD Cloud Home for a week. And of course things couldn't just go smooth and start working as I had hoped.

No matter what I do I can't seem to get access to the OMV server from windows. I have read the official guide and also check several different forum threads with similar issues, but following these guides haven't helped me. Whenever I try to access shared folder from windows I'm required to give username and password, and when I put in the username and password that I created in OMV web UI it says that access is denied.

Now I'm just really fed up about all the problems and issues. Is there any way to set the access privileges so that everyone accessing from my home network has complete acccess to shared folder at the OMV network?

Providing screenshot of the settings I believe is relevant.

Hi, thanks for your reply.

Yes I know omv4 is old and out of date, but when I was trying to install omv on my WD open cloud home omv4 was the only version I found "ready to install" so to speak. I'm less than a novice to all of this, and have absolute zero experience with linux and things like that. Believe me I tried at least 50 times to install a newer version of both debian and omv, but I couldn't get it to work.

Now the server is at least up and running.

I would love to update the system, but even following the guides step-by-step doesn't seem to be working for me. Is there a way to update to omv5 from within the current system? Or is the only way to once again remove everything and start over? Because I don't think my nerves can take that.¨

So unless it's a really really easy way to update to omv5 from omv4, it's just not going to happen. So if that's the case I dont care if the system is old, if there's huge security leaks or whatever. I just want to be able to access the system from windows. It's not like I plan to store nuclear launch files on there anyway.

What you think is easy is most likely complicated as *** for me. Like I said in the original post, I was fighting a war basically 12 hours per day for a week to get my HDD to finally accept the "plug-and-play" version I have now.

During this time I have read umpteen forumposts on how-to-install-omv-supereasy-guide, and none of them worked for me. I didn't install an old version because I really really wanted an old version. I installed it because it was the only plug-and-play version that seemed to work for me.

If I was skilled at these sort of things, I would probably find all this easy and think that people like me are stupid as well. But I'm not skilled at this, I'm less than a novice and came to the forum looking for help.

I didn't try once and gave up just to go on the forum and get someone to give me all the answers. I have read both here and at other forums, I have tried everything I could possibly think of three times over, just to make sure I didn't screw up.

For me "a really easy way" would be something like "Download this file -link-, open OMV web, go to updates and upload the file you downloaded - press update and wait 15 minutes"

That is about the level of knowledge I have about these things. But I haven't seen this option available anywhere when I have searched the forum for ways to install OMV on My cloud.

So I realize that I look incredibly stupid. And yet, I am submitting myself to looking stupid because I need help.
