Just a quick post to potentially save some time and frustration to my Windows Mobile 10 compatriots. In order to access the SMB share from your Windows Mobile 10 device, I recommend that you use Metro File Manager Pro which works great to manage files locally, in OneDrive and also in SMB shares. Oddly enough, the built in File Manager doesn’t support network shares.
If you get an error while trying to browse your share, check for the following event in the System event log for the Server service (srv):
The server’s configuration parameter “irpstacksize” is too small for the server to use a local device. Please increase the value of this parameter.
I was hitting that particular error every time the application tried to access a share that was residing on a 4TB thin Storage Spaces virtual disk.
You can apply the solution mentioned in this KB article and specify a value of 50. Once the registry was created with the proper value and the Server service restarted, I was able to access and browse the share successfully from my phone.
