SYMPTOMS
When you use the GetFileAttributes function and the SetFileAttributes function frequently on many files, you notice that file sharing on the network is slower than expected in Microsoft Windows Server 2003 Service Pack 1 (SP1).

Note Windows Server 2003 SP1 is included in x64-based versions of Windows Server 2003.

<div class="cause_section">

CAUSE
The problem occurs because the locking mechanism for an NTFS file system queue is changed in Windows Server 2003 SP1. This change adds more overhead to NTFS. This added overhead causes the decrease in network performance.
