Not reading client directory

[NMG]

Hello,
I'm using a function that reads the files from a client directory and works ok with client w95,w98 or ME but, working with XP, or NT returns the error:
"OpenDir: invalid argument (errno 22)"

The function is:

$file_dir=dir("//pc1/c/files/");
while ($archivo = $filedir->read())
{
$str_files .= $archivo;
}
$file_dir->close

I´m using apache 1.2.3 and php 4.2.3 on windowsNT server

I´ve tried changing the slashes (change "/" to "\") but the error persist
any ideas?

you might need to specify the drive letter

OK, but the problem is that the client is on the nertwork

Map a drive to it.
UNC will not work everywhere. =)
