Help: invalid class string instantiating

[Cameron Lewis]

System: Windows XP Pro SP2 with all the latest updates

Error Type:
Server object, ASP 0177 (0x800401F3)
Invalid class string
/index.asp, line 20

The code:
SET fs = Server.CreateObject("scripting.fileSystemObject")

This was working just fine up until I just installed Microsoft's latest
updates from their updates site. Now, suddenly, I'm getting this error
message on a very basic line of code. I cannot stress enough that this is
the ONLY thing I've changed.

I tried uninstalling and reinstalling IIS. No luck. I tried manually
registering scrrun.dll from windows\system32. No luck. I searched and
searched via google, and got lots of people running into the same problem,
and not actual solution.

Any help would be GREATLY appreciated. Please forgive me if I haven't
included some vital detail... I'll be happy to in a follow-up.

If you open RegEdit on the machine you are running this on, can you
find HKEY_CLASSES_ROOT\Scripting.FileSystemObject ? Under this folder
there should be a CLSID folder with the guid
{0D43FE01-F093-11CF-8940-00A0C9054228} (or similar) - can you find this
ID in HKEY_CLASSES_ROOT\CLSID? If so, there should be a folder
InProcServer32 with the path to the scrrun.dll file (in
C:\windows\system32\ on my machine). Can you verify that you have that
file?

How about creating another web page with the same code behind it (but
don't copy and paste - retype that particular line, just in case you
have some sort of string weirdness in there). Maybe that might help
you. Perhaps (for ultimate paranoia) the string is now case-sensitive
for some reason - try Scripting.FileSystemObject? (that seems highly
unlikely)

Or it could be a permissions issue, but it doesn't look like that is
the case, based on the message you are reporting.

I see the Scripting.FileSystemObject folder under HKEY_CLASSES_ROOT, but I
don't see an InProcServer32. Not sure how that should look. Could you
perhaps email me a .reg or something that I can look at? Or just post it
here as text, perhaps?

I see the scrrun.dll in windows\system32, but I don't know what the
InProcServer32 stuff is.

I tried running some very simple sample code with the object off
Microsoft's site, and even that didn't work, so I know it's not a simple
typo or anything.

I had also tried adding the internet user account to administrator, just in
case it was a permissions issue, but no dice.

Thanks for your help! It looks like I might just need to know what
InProcServer32 should look like in the registry to get this working again.

Well, I searched for scrrun.dll, and there is a
HKEY_CLASSES_ROOT\CLSID\0D43FE01-F093-11CF-8940-00A0C9054228
that points to the correct place in it's InprocServer32 folder.

I guess I"m at square zero again.

I love how Microsoft issues patches that break other parts of the system.
I'm frustrated beyond belief at this point, and there's absolutely no way
I'm reinstalling windows because of this.

I see you've already tried the big hammer for the Permissions case, but
here's an article that might help you track down a little finer for the
permissions:

http://support.microsoft.com/kb/q175804/

In it there is some useful instructions on turning on Auditing to see
what permissions are being requested (and perhaps denied?)

Gave it a try. I change the permissions. The minute I hit "apply" or "OK"
on any change, it reverts back to what it was.

My patience with this sort of microsoft stupidity is at ebb tide. I'm sick
of this crap.

open regedit.exe
go to this key

right click and choose Permissions...
set permission as follow:
. users read
