file_exists problem Windows IIS Network Mapped Drive

[Chann Becker]

My current setup:

WWW Server:
Windows 2000 Server, SP4
IIS5
PHP 4.3.4

File Server
Windows 2000 Server, SP4

WWW has a mapped network drive to an images catalog

p: = \\file_server\c atalog

There is a test file there called "file.txt" (p:\file.txt)

Trying to use file_exists to check for existance of this file. Other
functions depend on the results.

code example:

$fname = "p:\\file.t xt";

if (file_exists($f name))
{ print "File ". $fname. " EXISTS.<br>"; }
else
{ print "File ". $fname. " DOES NOT EXIST.<br>"; }

This function will return correct results when tested on a file on the
local file system, either c:\file.txt or d:\file.txt.

It will not return a TRUE value on file p:\file.txt or any other file
that is on a mapped network drive.

The permissions on the share are set to FULL CONTROL for EVERYBODY and
IUSR_machinenam e.

The permissions on the file are set to FULL CONTROL for EVERYBODY and
IUSR_machinenam e.

Any ideas?

I've read all the forums on php.net, devshed, phpbuilder, and anything
that GOOGLE returns.

Apearently there was a BUG 2 years ago, but since has been fixed. Not
that I could tell.
