Help!

I have programed a couple of vba functions using the fso
on a stand-alone machine successfully. Migrating to a
network based PC causes the following error

for the code:

Dim fso as Obect
Set FileSystemObj = CreateObject
("Scripting.FileSystemObject")

Error Message:
Run-time error '429': ActiveX component cannot create
object

I have tried to follow the Microsoft Knowledge Base
Article - 244264 on verifying driver versions, and all are
in sync.

Has anyone solved this one successfully?

TIA,
AlexJ
