This article was previously published under Q317761



SYMPTOMS
After you install BizTalk Server Service Pack 1 or BizTalk Server Service Pack (SP) 1a, you may notice decreased performance when you are using the File Transport. You may observe this decrease in performance regardless of whether the file path is local or remote.



CAUSE
This problem occurs because BizTalk Server SP1 and SP1a modify the File Transport so that each document is written to the disk from the cache as it is processed by the File Transport.



RESOLUTION
To resolve this problem, obtain the latest service pack for Microsoft BizTalk Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

299664 INFO: How to Obtain the Latest BizTalk Server 2000 Service Pack



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft BizTalk Server 2000 Service Pack 2.



Configure Disk Caching
When you disable disk caching, you avoid the loss of data during interruption of service failures, such as a power failure. When you disable disk caching, you degrade the BizTalk Server performance.

To enable or to disable disk caching:
 * 1) Click Start, point to Settings, click Control Panel, double-click Administrative Tools, and then double-click Computer Management.
 * 2) In the Computer Management tree, expand Device Manager.
 * 3) In the detail pane, double-click Disk Drives.
 * 4) Right-click the drive on which you want to configure disk caching, and then click Properties.
 * 5) In the   Disk Device Properties dialog box, on the Disk Properties tab, clear the Write Cache Enabled check box.

NOTE: This procedure is a computer-wide change of the disk cache properties.
