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.
