SMB shares some work, some dont (Windows 10 Fall creators update)

Added by Andrew Jakobs about 5 years ago

Hi,

After reinstalling Windows 10 Fall creators update I have problems with some shares giving me an SMB Error 0xC0000205 (I'm using the latest(nightlybuilds?) PS3 version, using the internal updatefunction)

To Get SMB working with Movian again I had to first add SMB 1.0/CIFS File Sharing Support through the Windows features, that made Movian be able to connect to my computer again.
then I just used the 'advanced sharing' button on the properties windows in windows to add a share (root drives). I did this for 4 drives (one internal, 3 USB drives).
Now I see all shares in Movian, but only one does actually work, the other I get SMB Error 0xC0000205
I've already set the following registry settings as some other topic said that it might work:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size => "3"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache => "1"

But sadly that didn't make any differences.

I've also got a Windows 10 Fall Creators update instance which was upgraded all the way from Windows 8, and there the shares do work.
I'm not really up to networking/samba settings etc. and I've already googled a lot, but couldn't find a solution.

Hope some of you can help

ok, right after I wrote the question, I got the idea of checking the Event Viewer..
And low and behold, it actually had the error of what was wrong:

The server's configuration parameter "irpstacksize" is too small for the server to use a local device. Please increase the value of this parameter.

So I rebooted to my Windows 10 instance which still worked perfectly, and checked to see if that one had the setting.
And yes it did, whereas my newly installed windows 10 didn't.
So after I added the following key, it all worked again.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\IrpStackSize (DWord) = "32" (Hexadecimal)

So I hope this might help other people who had the same problem as I did..
Now I just hope Movian is gonna support the newer SMB protocol so I can remove the unsafe SMB1 from my Windows 10.
