I can see the share in XBMC on ATV2, but when I try to go into it, I get Invalid Argument message

This is a share on an external HD. Shares on internal HD are fine.

Here's what solved it for me


The irpstacksize parameter can be increased by changing the registry value.

To change the registry value

Using Regedit, open the following registry key:
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\IrpStackSize
In the Value data box, type 15.

The default size is 15 stack frames. Each stack frame is 50 bytes. If the value is less than 15, advanced users can safely set it back to 15. If 15 is too small, try increasing the number by increments of 5 until this event is no longer logged. Changing this registry key requires a restart of the Server service.
