James, The CHM file was on my local drive and I tried it on different machines. I also had a similar problem with network drives before, but this one was different. I think you are right, it has something to do with IE trusted zones.

GS, thanks for the tip.

Had to roll this fix out and used a registry key change.
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
“MaxAllowedZone”=dword:00000001
Worked for our XP SP2 computers….

I’ve often found that Vista/Windows 7 don’t like displaying CHM content from a network drive – move the file locally and the OS is happy. Presumably something to do with IE trusted zones?
