ASP File System Object permission?

I am trying to check for a file on a remote server.  Everyone has read and execute permissions to the folder and files I am trying to check.  I believe the code is correct because it works when I logon to the IIS server and load the page, but not when I load the page on a computer other than the IIS server.  I wonder if it is a permission thing or setting? Thanks in advance for your help.  Here is my code:

<%'Check to see if photo exists
dim objfso
dim fname
dim lname

fname = rs.Fields("FirstName")

lname = rs.Fields("LastName")

set objfso = server.createobject("Scripting.FileSystemObject")
strFile = "\\taifl\common\securitas\" & lname & ", " & fname & ".JPG"
if (objfso.FileExists(strFile))=true Then %>
   <a href="<%=strFile%>" target="_blank">
   <img src="\\taifl\common\securitas\<%=lname%>, <%=fname%>.JPG" width="160" height="107" align="top" border="0"></a>

<%end if

set objfso = nothing

Try changing your website authentication to anonymous account and check if it works.
Give permissions to IUSR_XXXX in IIS Server

I assume you have Anonymous Access and Integrated Windows authentication selected in your authentication Methods for the website, and the Anonymous User account is IUSR_XXXX.

If so, the reason you can get to the files when on the webpage from the server is because it will be using integrated windows authentication. For the anonymous user account to access the network files, the anonymous user must be a DOMAIN account not a local account. Giving Everyone access to files only gives authenticated domain user access to the files, so website users must be running in an authenticated DOMAIN account

If the files were on the local server and not on the network, you would be able to get away with the IUSR_XXXX account

I tested FSO with IUSR account on local files and still no love.  If that were the case it should have worked when I tested it with local files.
Can you try creating a virtual directory in your IIS server to the remote folder?

FSO doesn't even work locally.  Though, that may be an option once I get it to work locally.
But on your first comment that it worked when you logged in locally. Can you tell what is the exact error you are getting?

Sorry for the confusion.

It worked when I logged on to the server locally.

When I logged on to another computer it did not check for the file on the remote server or local IIS server.

I hope this makes sense.

I did find out that the account is not being used as an anonymous account.  Maybe that is it.

I have had this problem. Maybe the solution is one of the above but the one that worked for me was this:

Remove Script Blocking from Norton Antivirus.
