mkdir with PHP 4.3.4 and IIS 5.0 on Windows 2000

I have a peculiar problem in one of my scripts. I cannot mkdir from the script, but from a test script, the same exact code works. test.php contains: <? include('func/mkdirs.php'); // this function recursively checks and create a directory tree. I know it works fine. $directory = '\\\\seint16\\TechComm\\Ceos\\Dang\\'; echo "Attempting to mkdir<br>\n"; mkdirs($directory,0755); $dir_object = @dir ($directory) or die ("Could not open a directory stream for <i>$directory</i>"); print_r($dir_object); $dir_object->close(); ?> I have another script that takes some input from the user, namely to be a new sub-folder to create on the destination directory. Just to eliminate the possibility that the code from my script is not the problem, I commented out everything that had to do with what I really wanted. In its place, I substituted the above code from test.php. When I call test.php, the directory is created fine. However, when I execute my problematic script, which now contains the exact code, I get Attempting to mkdir Could not open a directory stream for \\seint16\TechComm\Ceos\Dang\ This is quite puzzling, since the exact same code should work in both scripts, but it's not! Any help, please! Thanks, Dang Nguyen
