    I'd just like to mention that if you have your IIS server locked
    down such that the IUSR_machine account has no access
    (explicit deny) to %systemroot%\system32\  you'll run
    into an authentication problem.
    
    You'll have to grant read access to the file MSVCP60.dll
    for the IUSR_machine account and may have to grant a
    similar permission to ISCF.dll in your cfusion\bin directory.
    
    For those of you who still allow the use of the Everyone group
    on your machines or do not use explicit deny ACLs for the 
    IUSR_machine account, this will not be an issue.
    
    I'd also like to state that I wasn't impressed with the often
    urged "upgrade to v5.0" to fix the problem and how "nice" it
    was of them to supply fixes for three previous releases. 
    Like they're doing us a huge favour.  I would certainly like
    to know more details.
