DP-S1 can’t see shared folders on Win10 PC USB HDD (solved)

[sub3R]

I’m not sure if this particular solution has been posted on this sub-forum before.

For anyone having problems seeing a shared folder on a USB connected Ext HDD connected to a Win10 Laptop (or PC), the following may help.

From our DP-S1s I could always see & play recordings stored on shared folders of a 2TB USB Ext HDD when it was connected to a WinXP PC (DP-S1s were connected via Ethernet LAN). However, I found this wouldn’t work over the same LAN on my Win10 Laptop using the same USB Ext HDD & same DP-S1s.

A Google search came up with a solution that worked:

The following

Code: Select all

IRPStackSize      REG_DWORD      0x00000020 (32)

was missing from the registry & had to be added to the registry under:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

This topic has more information.

The relevant instructions from jopmoro ’s post in that topic are listed below:

1) Run regedit.
2) Navigate to the following key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
3) In the right pane, double-click the IRPStackSize value (if it exists, if not, see below). In the Value Data box, type a Hex value of 20 (32 decimal) and then click OK.
4) Close the Registry Editor and restart the computer.

If the problem persists after you complete the preceding procedure, try to increase the value of IRPStackSize even more. The maximum value for Windows 2000 was 50 (0x32 hex), so you should stay below that.

How the create the IRPStackSize value:
1) In the Parameters folder of the registry, right-click the right pane.
2) Point to New, and then click DWord Value (32 bits).
3) Type IRPStackSize exactly as it is displayed because the value name is case-sensitive.

Important: I wouldn’t recommend making any changes to the registry unless you are aware of the consequences if something is changed or added incorrectly. When you exit from regedit, all changes & additions are saved without any confirmation. A backup is recommended first.

From what I have read, this issue appears to go back as far as Win7.

I must be luccky, as that registry entry isn't needed to allow my DP-S1 to access a USB-based share attached to my Windows 10 Home edition computer.

That’s interesting. Obviously there is something different between our setup or settings.

I tried everything I could think of to get it working & that was the only change that worked for me. Before the registry change I could see the shared top folder of the Ext USB HDD (NTFS format) but not the files or sub-folders. However, all shared folders & files on the internal HDD worked fine before & after the registry change.

This particular laptop origally came with Win8 & from memory the same Ext USB HDD didn’t work with that from either DP-S1. Yet with WinXP on my old desktop PC it always worked perfectly.

Both the WinXP PC & the Win10 laptop were connected identically; (all Ethernet LAN, no wireless) PC > switch > router/modem. One port of the same switch goes to one DP-S1 via Ethernet LAN & another port of that same switch goes to another switch then to the 2nd DP-S1. All devices have fixed IP addresses.

... Before the registry change I could see the shared top folder of the Ext USB HDD (NTFS format) but not the files or sub-folders. ...

That normally indicates that the user authenticated for the share (equivalent to Connect As... when doing a Windows-to-Windows share connection) has access to the sharepoint, but not to the folders and files being shared.

It does sound like that, but under permissions ‘everyone’ is set to read & execute ‘this folder, subfolders & files’. Perhaps that should be ‘full control’ instead of ‘read & execute’, but all the shared folders on the internal HDD that worked before & after the registry change are only set to ‘read’.

I’ll have a play with that later when I finish setting up the T2 – so far the the WAF is about 1 out of 10.

At Dennis's (sub3r's) suggestion, I've moved posts here relating to his "new user" experiences with his T2 to New T2 owner’s concerns about Fonts, EPG, LCNs, ....

A few posts relating to the move and unrelated to the topics at hand have been deleted by their authors.

Thanks Peter.

Win 10 home, new computer, this fixed it for me, thank you, after hours of googling

Oh ya, don't forget to do a restart of the win10 machine
