Sap Help Configuration Error

Hi Experts,

We have installed Sap Help Library PlainHtml in our Server Ecc6 Ehp5 (Material No - 50123024). We are able to access the Library only from the server where we have installed library, through Gui. But when we tried to access the Sap Library outside the server  from the Gui we are getting the below error.

Parameters Maintained in SR13 :

PlainHtmlFile

Variant : HTML (File) 6.40 English

Platform : WN32

Area : IWBHELP

Path : H:\library_plainhtml\PLAINHTM

Language : En

Default : Checked

Help us how to move forward.

Thanks in Advance.
