Ran into something interesting today. We have an application that the majority of it is run from a network drive. It looks like not too many people ever access the help system because it wasn't working. After some testing, it was discovered that the same help file copied to the local C: drive worked fine.
There is a security setting in Windows (at least 2003 server) that disables the ability to use remote .chm help files. Here's a way around it. Create a .reg file like this. Or use the path to create it manually in regedit.exe.
<-- Start Reg File -->
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001<-- End Reg File -->
Save this somewhere and double click it. After the file has been merged, anyone on the computer will be able to view .chm files off of network drives!
