Slow network performance occurs when you select a file on a share that uses NTFS

Article ID: 265396 - View products that this article applies to.

This article was previously published under Q265396

SYMPTOMS

When you select a file on a network share that uses an NTFS file system partition, extra Server Message Block (SMB) packets are sent on the wire. This behavior causes overall slow network performance.

The same issue occurs if you browse the network, and you position the mouse cursor over one of the files; however, this issue does not occur if you use a Microsoft Windows NT 4.0-based client computer.

CAUSE

This issue occurs because Microsoft Windows Explorer tries to open NTFS streams on the volume to get extended information about the file, for example, title, subject, comments, and source author. All of this information for the file is stored on the volume.

Slow network performance when you open a file that is located in a shared folder on a remote network computer

Note For the best performance, perform step 6 after you apply Windows 2000 SP4 on the client computer.

Note These additional steps are required because if you select Show pop-up description for folder and desktop items or if you do not select Use Windows Classic Folders, this creates extra traffic on the network, even after you apply the hotfix.

These attempts to open hidden data streams are designed to extract the data required for displaying pop-up descriptions, the Explorer status line, and certain Properties dialog pages. After the hotfix is applied, the Summary, Custom, and Security pages of the Properties dialog will never be displayed, because it is not possible to create these Properties pages without the data from the eliminated traffic.
