QuickFix: reinstall docker4win, if that doesn't help uninstall again and switch to edge-channel version

[dimitriadams]

I uninstalled docker4win, rebooted, installed the edge-channel, rebooted, tried to share again but still no success. The logfiles shows that mounting seems to be successfull with SambaShare, but with NamedPipes it gives an error: Key already exists in dictionary...

I tested this again, and was able to share my C: drive in the latest edge build, where I wasn't able to on the stable build.

Have you tried the reset function? Try resetting to the factory default

[dimitriadams]

Just tried the 'Reset to factory defaults', but still no sharing

[gesch]

Having the same issue with stable and edge. Tried different combinations of installs, resets and reboots. No Luck yet. Currently It is not possible to share any drive on windows.

[patelmaulik]

Same issue on Win10 Pro. Tried everything in the book

1. re-installing file & print sharing, re-installing drivers
2. manually opening ports although docker has already added firewall rule
3. reset, reboot etc..etc
4. edge & stable channel

Still no joy with shared drives.

[mohahn]

The same here. Using

• Docker 17.03.1-ce-win12 (12058)
• Windows 10 Pro, latest Version 1703 (Creators Update)

It seems a bit reproducable for me. Perhaps anyone can confirm this. After every re-install of Docker or "Resetting to Factory Defaults" I can add a shared drive, by providing credentials. But when adding another drive or disable and re-enable existing share, the same behaviour as above happens: after providing credentials when clicking "Apply" the shared drives are unselected again.

I want to mention, that Docker from Edge channel does not work for me, as it fails on building image with error oci runtime error: container_linux.go:262: starting container process caused "exec: \"/bin/sh\": stat /bin/sh: no such file or directory" (could be related to this)

What seems to work for me is: first, share complete drive in Windows explorer (via extended share, in german: "Erweiterte Freigabe") with all permissions to admin only. After that I can add this drive in Docker settings without error. I did not modify any other Windows or firewall settings like others suggest, only file and print sharing is enabled. Can anyone confirm this?

[jasonbivins]

Hi @dimitriadams @mohahn This is an issue in the Stable build - have you tried the latest Edge build? We just released one earlier today, 17.06 rc4 that should resolve this for you. Please try it and let me know how it goes.

[dimitriadams]

I just installed the 17.06 rc4 version but still the same results. I did a 'Reset to factory defaults' to be sure but no shared drives.... :-(

[mohahn]

@jasonbivins have u read, that after installing Edge a build of images fail? Nevertheless, even with Edge, after fresh install I can add a share (like in Stable) but when editing a share or adding a new one, all shares are disabled again. For me the same behaviour like in Stable.

Docker Version: 17.06 rc5

Mine Windows account is linked to the Microsft. In the lusrmgr.msc i can see that user password is marked as "User must change password at next logon" and this option can't be changed.

This worked for me as workaround:

1. Create a new local Windows user (best to use usrmgr.msc)
2. Set strong password (you will use it only once, so write it down to password manager)
3. Check "Password never expire"
4. Add user to Administrators group
5. Open Docker setting and allow drive sharing
6. Use newly created user credentials

[lgaida]

I got this issue again, after changing my password on windows. And i remember this was also the case when i got this issue last time. I'm requested to change my password every 2-3 months for security reasons. Looks like i have to reinstall Docker again.

While the suggested solution from @pavelmaca might work there will still be users (like me) who can not simply create a new user on their system. Docker should not corrupt shared drives when the user password has changed. Imo docker should somehow notice that the password has changed and ask for the new password to allow the shared drives. Or atleast uncheck the shared drives so a user can spot the problem and then check the drive again + authentication.

[dargmuesli]

Try the newest Edge build. Version 17.06.1-ce-rc1-win20 (12818). The issue is fixed for me there.

[dimitriadams]

I just tried the new Edge build, still no luck in sharing drives.

[liri2006]

Faced the same issue, even with Edge build. Providing credentials of other admin user indeed works, but in this case this "other" user should have access to current users's folder in C:/Users/{currentUser}

[kirisky]

I ran into the same problem today.
My environment is Windows 10 Pro and docker for windows.
My port 445 is blocked by the firewall. I tried many methods, but they didn't work.
Then I found my firewall has two "block the connection" rules. They banned port 137, 139, 445 and 3389.
The rules' names are "20170415漏洞" and "20170415漏洞UDP".
So, I opened the window of the rules‘ property and turned on the "local principals" tab.
Then, I added my windows account to the "Exception."
Finally, I solved this problem.
It spends some times of mine.
I hope my experience could help someone.

Still happens to me. I have a PIN set, but docker keeps asking for password on mounting drives. If I shut down docker and restart it, docker lets me mount the drive without asking for password again.

[dashesy]

Same as @kumarharsh After restarting the docker the drive is shared without askign for password!

[namnh06]

I knew what happen guys.

In my case, after remove xampp in my computer, I can not share drives any more. It's block the 445 port, guess that.

Just find this one and disable it !

Ultimate Solution:

1. Open Powershell as Admin
2. Run this command Set-NetConnectionProfile -interfacealias "vEthernet (DockerNAT)" -NetworkCategory Private
3. Now go to docker settings
4. Click on shared drives
5. Check the drives you want to share with docker
6. Click Apply it might ask for password
7. Enter your password and Congratulations!!

DONE

Reset to factory settings worked for me.
I hate Windows for this kind of time waste

[Yavdhesh]

I had to reset it to factory defaults.
restarted, then checked those drive, it worked.

पुन: शुरु किया, तब ड्राईव साझा हो गया ।

[Twosmiles]

I've tried each and every recommendation here and in other issue trackers. My problem was that the windows service called "Server" (Thank you microsoft for that) was not running and actually deactivated.
After starting it, the sharing worked just fine

[Fieel]

I got a popup after running docker-compose up - nginx mysql, inserted my microsoft account credentials and it worked. I had to try multiple times, though.

[stephen-turner]

This is fixed with the new filesharing implementation in 2.2.0.3, so closing this ticket.
