Hi,

I'm afraid deploying some registry settings is your only option.

Deploying the setting in the registry file listed below will solve
the problem as long as your network drive or UNC path is defined as
"Local intranet zone" (it should be).

To see what zone you have for the path, in Explorer, select
"Status Bar" under the View menu and then go to the folder where the
help files are located. If it says "Internet" in the Status bar, you
will need to add your domain or server to the "Local intranet zone".


--------------------8<----------------------
REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000002

--------------------8<----------------------

The setting above will open up for Local Machine zone, Local intranet
zone, and Trusted sites zone, but *not* the Internet zone.

Thank you. Your fix steps are much simpler and easier to understand than
what I found on MS KB. I guess I just needed an interpreter. This shouldn't
be too difficult to deploy.
