I've tested an install of OMV on a W10 desktop that allows you to deploy Hyper-V and it just worked, in fact I compared that to to running VirtualBox. Hyper-V was a bit odd in setting up the network (I had to google that) but it worked.
Worked better than ESXi?
That should be straightforward, I was running a Hyper-V with 4 Windows VM's, when I utilised the old server to use OMV it was as back up server, backing up each of the VM's, but I never had ESXI in the way.
So your Windows server is a standalone and OMV is on ESXI
Yes that is correct. My technician at this company tried installing OMV5 on Hyper-V and not sure what he did, but he lost everything we initially transferred over to the OMV server. All data was unrecoverable. My research showed that Hyper-V and OMV5 didn't play nicely, that too many features were missing in the Hyper-V (vs ESXi), so I decided to have a go at it myself using ESXi. It has been a frustrating journey thus far to say the least.
Now where did I put that setup guide? 
It should yes as mine was a DC, but why do you need to run a Windows server
II have an existing Windows Server who's database backups I want backed up and stored to the OMV5 server securely. Neither the OMV5 server or the Win2016 server are on the domain. I just have a big PowerEdge r720 server with 32tb storage space for my company backups, and in using ESXi, I can eventually run other apps on it if I needed to?
Yes, the user cannot belong to the domain admin group, but this is going back 4 years, I had a user name to log on to the server with admin rights on the server, I could add a user, I could set up software deployment etc. But if there was any need to do anything related to AD then I had to log on as the domain admin.
The default login for a Windows server is admin and this is usually the domain admin, there was another user some time ago with a similar issue he overcome the problem by adding ntlm auth = yes to extra options in SMC/CIFS on the OMV server. This is like enabling SMB1
Enabling SMB1 which is very insecure?. Fortunately the server I want to transfer files from is a stand-alone and not in the domain., so the similar user might work? I have to start over now with OMV5 setup
That's interesting, a domain user particularly the domain admin I would expect to fail, but a local user belonging to the admin group (not domain admin) should work.
I used OMV with server 2012, when we replaced the server, the old server was deployed with OMV as a backup using iscsi target. I set up a new user on the Windows server and used the same user name on OMV and it worked well.
You set up a new "local" user on the server?
What user are you logging into the Win2016 server
I have tried both a domain and non-domain user, I just wiped the entire VM. I have tried so many things, probably best to start over (if possible)
It's an interesting idea, but I am trying to transfer files FROM my Win2016 server to the OMV5 secure share. Incredible that there is not an easier way to do this?
I have curiousity. Is the problem only with OMV or any Linux system? Have you tried from Ubuntu, Linux Mint ...?
Good question. I used "best practices" using debian 64 bit as the OS. Haven't tried anything else.
I found this.
[HOW-TO] Connect to OMV SMB shares with Windows 10 and Microsoft Servers
I downloaded the document and read it (as best I could, in my poor English).
It is old but it seems that this problem comes from a long time ago. Which reinforces the theory that the problem really is in Windows Server and its historical restrictions in its battle with Linux.
If you want to read it, notice that it talks about domains, and also configure it in OMV as WORKGROUP.
I've read it - still no help.
Soma posted a link in the other thread.

I just read at the bottom of the page that someone managed to solve it by enabling insecure guest access. I don't know if this would solve your problems. You saw it?
Yeah I saw that, tried it, still nada
The OP of that thread got it somehow, and I don't know how. I hope he still responds, it is a recent thread. We should have asked him how he did it before we considered the thread resolved. It is a pity that the threads often do not provide all the information for the one who comes after.
In any case I am convinced that the problem is with Windows Server. Can you check if the domain configuration influences the problem?
I am also convinced that is it the Windows server as well. I have been working on this for over 2 months now with no resolution. I have tried everything from regedits to allow guess access, allow insecure guest access, tried SMB1-3 - everything! I can get to public, non-password folders no problem, it's the protected folders that I can't seem to into. I get the usual windows security popup (which I don't think I would be getting since it's a samba share) and I have had many very helpful volunteers on here do screen shares with me on here to no avail. They too scratch their heads in disillusion. This seems to be a common topic on OMV forums, yet no one seems to have a resolution. It's just mind-boggling that windows 7, windows 10 machines can connect to this protected share, but not my server?
OMV5 SMB NOT ACCESIBLE ON WINDOWS SERVER2019
Take a look here, maybe it's the same problem.
I would not configure SMB1, it is insecure.
I tried this (many times) no joy! SMB1 is *NOT* enabled...
now after entering admin user name and password it shows me the folder, i think by enabling guest access it worked
You enabled guest access where?
Well I have OMV5 on ESXi with just two shared folders; one for staff, one for private. All machines BUT my Windows 2016 server can attach to both the staff (unsecured) and private (secured) folders with the proper credentials. Only the Windows 2016 server cannot access the private folder. I attempt to connect and I get the typical windows credentials popup. Once I get past that, I can't log onto the private share. I have tried the reg edit of the allowguestaccess thing, but still nada. I have SMB2 enabled, but I did try SMB1 and 3 on the server and still nothing.
I am going to try this one last time before giving up. I have a setup of OMV on ESXi on a Dell PowerEdge r720 server everything is set up and working properly except for one thing, which for me is the most important thing, I need a secure connection from a Windows 2016 server to a shared folder on the OMV. I have tried just about every configuration I can think of and with the help of several others on these forums have tried just about everything imaginable and I still cannot connect to a secure folder via the 2016 server. Does anyone on these forums have experience with Windows 2016 server connectivity issues, and has found a way for this to work?
I have been working for two weeks trying to setup a simple OMV5 on ESXi server. In a nutshell I have pretty much everything setup and working. I have two shared folders: PUBLIC and PRIVATE. Everyone can see and read/write in the PUBLIC folder, no issue (although I had initial issues trying to get my Windows 2016 server to write to it) So the issue is, everyone can see, read and write to the PUBLIC share. Everyone can see, read and write to the PRIVATE share, except my Windows 2016 server, which is the primary reason for having this private share.
Ideally, I would like everyone to access the public folder, no issue there. However I would like the "PRIVATE" folder to be accessible and have only a single user (or group) be able to write to it. I have read probably over a hundred articles on here, google lookups, you name it. I have tried just about every suggestion I found on this forum. Still everyone has full access to everything, except the one machine that absolutely needs it - alone! Now I am a "windows guy" and perhaps I do not understand all the linux/samba permissions, so I am desperate and begging for some assistance here.
Anyone?
OMG! Nearly 2 weeks of research, and finally I found an answer to my issue! Thank you so much crashtest
I spoke too soon. While I can now access the shared folder, I cannot write to it.

marcusp I am afraid I will need some additional help. How best to contact you?
Can you assist?
