I use the filesystem object in several of my ASP applications, on IIS6 servers the FSO won't work, when I try the same code on IIS5 servers (with the same filters) it works fine. FSO returns no errors, just lots of "falses" like I'm referencing an empty var. I've researched the problem and can only find people having this problem when anti-virus apps block the filesystem object, or security permissions block access to the DLL required to run FSO. I don't know what DLL is required to run FSO, or what permissions are required on the DLL or if the DLL is even the problem. All I can really say for sure is FSO works in IIS5 and not in IIS6, there must be a reason. We're supposed to be upgrading our servers soon to IIS6 so I need to find out how to get IIS6 to work with my apps.
