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.

MORE INFORMATION
Follow these steps on all client computers that use the products that are listed at the beginning of this article:  Install the hotfix, and then restart the computer when you are prompted. On the Tools menu in Windows Explorer, click Folder Options. In the Folder Options window, click the View tab, and then make sure that the Show pop-up description for folder and desktop items check box is not selected. Click the General tab, and then click the Use Windows Classic Folders check box. Click OK to close the Folder Options window.</li> Follow the steps in the &quot;Resolution&quot; section of the following Microsoft Knowledge Base article:

829700 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.</li></ol>

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.

When you a select a file, the following information is displayed on the wire:

<pre class="fixed_text">SMB C NT create & X, File = \dnscrcli.lib SMB R NT create & X, FID = 0x800f SMB C transact2 Query file info, FID = 0x800f SMB R transact2 Query file info (response to frame 5) SMB C NT create & X, File = \dnscrcli.lib:Raec25ph4sudbf0hAaq5ehw3Nf:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:Raec25ph4sudbf0hAaq5ehw3Nf:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:{4c8cc155-6c1e-11d1-8e41-00c04fb9386d}:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:SummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:Docf_SummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:SummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:Docf_SummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:SummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:Docf_SummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:DocumentSummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND SMB C NT create & X, File = \dnscrcli.lib:Docf_DocumentSummaryInformation:$DATA SMB R NT create & X - NT error, System, Error, Code = (52) STATUS_OBJECT_NAME_NOT_FOUND

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.
