Network drive mapped as 'X' can be seen be not accessed

I have 2 NAS drives for Data Storage attached to my Router and rather than Map the drives I have better luck Mapping the Public Folder on those drives. And I can access those Folders from any wired or wireless computer desired. I haven't had a need to install Network versions of programs on those drives, most likely would need a Server machine to do that.

Hey ValiantSaint,
Try adding/editing the two registry entries in this link - https://support.microsoft.com/en-us/...ItMyselfAlways

I'm not sure what has and hasn't been set on the shared information, as it's all been set up by someone else. How did I check?

See this tutorial - Share Files and Folders Over a Network in Windows 10 | Windows 10 Tutorials

Note: Option 6 / Step 3 - In the Properties Dialog > Security Tab is where you check the NTFS Permissions

I did look at that article earlier when I was struggling to get things back to normal at work. I couldn't find the registry entries that are listed in that document on one of the machines. Did you just add/create them? (Is there a registry add-on that would create these commands automatically?
And would I have to do this on all the machines? Or just on one, or the main PC?

1. If the registry entries aren't there you have to create them, per instructions in that link.
2. No registry add-on that I know of, but I guess you could create your own if you know how ... I can't help with that
3. I 99% sure you make the registry changes on the Main PC and I would do that first, before adding them to the other PC's.

Note: After editing the registry, reboot PC !!!


EDIT: After re-reading that link, I think you do it on the PC that is having trouble connecting .. sorry about that ... I don't think adding/editing those registry keys on any other PC's will cause any issues

Well, I've added those registry entries to two of the three PCs and now I can't see the X: drive on the secondary PC at all! Oops! Both PCs have been restarted......

Not sure why that would happen. Can you remap the drive ?


FWIW ... I have two Win10 Home PC's and even tho I wasn't having the issue you are ...
1. I added those two registry entries to both my PC's and rebooted them.
2. My mapped drives on both PC's still show and work.
3. You can use the following script to compare the Lanman/SMB registry setting on your PC's.

Code:

Note: The following script ....
1. Makes NO changes to your PC
2. It creates a .txt file on your Desktop (Assumes your Desktop Folder has NOT been moved)

Open PowerShell as Admin. Copy/Paste the following, making sure to hit enter after the last line.

$(
write-output "CHECKING LANMAN/SMB FOR COMPUTER $($env:computername) @ $(get-date -format g)"
write-output "==============="
write-output "LANMAN SERVER"
write-output "==============="
Get-ItemProperty -Path HKLM:SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
write-output "==============="
write-output "LANMAN WORKSTATION"
write-output "==============="

4. Here are my Lanman Server/Workstation and SMB Client/Server registry settings.
