How to View HTML Help Over a Network
By default, Windows does not allow HTML content from help files to be seen across a network. You may override Windows to view HTML over a network by making (or modifying) registry entries on each Windows workstation that needs access.
To allow HTML help to be seen over a network, go to HKEY_LOCAL_MACHINE\Software\Microsoft\HTMLHelp in the registry.
- Under that, there should be a 1.x key. Open that (or create it).
- There are two keys that need to be there. ItssRestrictions and HHRestrictions. If they are not there, create them.
- Each of these two keys needs a DWORD entry made called, MaxAllowedZone. Set it to 3 or 4. (Try 3 first. If that doesn't work then use 4.)
Next, go to HKEY_LOCAL_MACHINE\Software\Microsoft\WinHelp in the registry.
- That key should exist. If not, create it.
- There needs to be a DWORD entry made called, AllowIntranetAccess. Set it to 1.
With those entries made, you should be able to see the full context of the HTML help files across your network.
