Solved Network shares other than Public inaccessible Win8.1

I am trying to share a folder over a local network so I can access it from my Android device.
I am using ES filebrowser to access the computer. I have included my user creds when connecting but the only share available is the Public folder on C:, while I have other shares on a different (external USB HDD) drive that give me errors.

The error I get from ES is (Login fails) This may be caused by: WLAN is off; SMB is out of network scope; IP is invalid; Blocked by firewall; SMB service is off.

I have tried connecting from another windows pc using the same credentials and am able to view all the shares.

Edit: After creating new shares on local drives it seems the only shares that are unavailable are ones created on the external drive.
Also, trying to connect to this drive on Ubuntu gives: Unable to access location - Failed to mount Windows share: Invalid argument.

The solution was to increase the IRPStackSize parameter for Lanmanserver through the registry.

The key is

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

Create a new DWORD called IRPStackSize (if it doesn't already exist). Set it to a decimal value of 18 and increase incrementally by 3 until you can access the share. You will need to restart the "Server" service or restart your PC after every change for it to take effect.

Changes in IRP Stack Size in Lanman Server
Description of the IRPStackSize parameter in Windows 2000, in Windows XP, and in Windows Server 2003

The default value is 15. I set mine to 31.

Thanks for this post. I am having trouble scanning from a Ricoh Machine and after around 20 hours of trouble shooting tried this.

Any reason why 31 instead of 30? I used 31 since that is what you used and seems to work.

EDIT: this did not solve my problem. I went ahead and deleted the added Dword so it goes back to default.

thanks,

Mike

well, this fixed the problem for access from ES File Explorer. but then I tried to access from an Openelec box and I had the same problem again. I disabled and re-enabled the share, added another user, and now ES File Explorer can't access it again either.

I even tried 100 and the event viewer still said irpstacksize was too low! lol
