OS - Windows XP with NTFS and IIS 5.1
I have set write permission in IIS to all files located in Inetpub\wwwroot\.

my problem:
It all depend on what filesystem i'm using.
If i use FAT32 everything is all right, i can create new files or write data into them.
But when i'm using NTFS i can't create new files or write data into them. PHP report that it doesn't have permission on the files.

script:
fopen("sample.txt", "a");
flock($fp,2);
fwrite($fp, "bla bla bla");
flock($fp,3);
fclose($fp);

I had the same problem in Windows 2000 and now i have it in Windows XP too. So, where's the problem, in IIS, PHP or in me?

Thank you.
