Microsoft does not support the use of FAT file systems or FAT32 file systems with Internet Information Services (907733)


The information in this article applies to:

  • Microsoft Internet Information Server 4.0
  • Microsoft Internet Information Services 5.0
  • Microsoft Internet Information Services version 5.1
  • Microsoft Internet Information Services version 6.0

INTRODUCTION

We do not support the use of FAT file systems or of FAT32 file systems with Microsoft Internet Information Services (IIS).

MORE INFORMATION

Web Server administrators who use Internet Information Services and FAT file systems or FAT32 file systems should convert the file systems to NTFS file systems. FAT file systems and FAT32 file systems are available on Microsoft Windows operating systems for legacy and compatibility reasons for some types of applications. However, FAT file systems and FAT32 file systems do not have the modern security features that we require to help make the Web server secure. NTFS file systems provide several security features that we require for the Web server and that FAT file systems and FAT32 file systems do not provide.

Therefore, we recommend that all Web server administrators convert all FAT file systems or FAT32 file systems to NTFS file systems.
