On a Windows Server 2003-based computer, you must turn on the
Enable advanced performance feature for each hard disk that has write caching enabled and that has its write cache protected against accidental loss of power. Additionally, you must configure several registry subkeys.
On a Windows 2000-based computer, after you install the hotfix and then restart the computer, you must turn on the Power Protect write cache option for each hard disk that has write caching enabled and that has its write cache protected against accidental loss of power. Additionally, you must configure several registry subkeys.
Step 1. Turn on the "Enable advanced performance" feature in Windows Server 2003 or the Power Protect option in Windows 2000
Windows Server 2003
To turn on the
Enable advanced performance feature on a Windows Server 2003-based computer, follow these steps:
Warning We recommend that you only enable the
Enable advanced performance feature for disks that have a backup power supply. This setting improves disk performance, but it also increases the risk of data loss if the disk loses power.
- Click Start, right-click My Computer, and then click Manage.
- Under System Tools, click Device Manager.
- In the right pane, expand Disk drives.
- Right-click the disk drive that you want to configure, and then click Properties.
- Click the Policies tab.
- If the Enable write caching on the disk check box is selected, click to select the Enable advanced performance check box.
- Click OK.
Windows 2000
To configure the Power Protect option in Windows 2000, use the Dskcache.exe tool.

Obtain the Dskcache.exe tool to configure the "Power Protected" write cache option
When you run Dskcache.exe without any parameters, the current write cache settings for all hard disks are displayed. For each hard disk that is currently installed on your computer, the following information is displayed:
Disk device :
\\?\\
<SCSI DEVICE ID>
Current Settings :
Write Cache is [ enabled | disabled ]
Power Protect is [ enabled | disabled ]
To turn on the Power Protect option on a hard disk, use the
p
command-line switch.
For example, to turn on the Power Protect option on drive C, type the following line at the command prompt, and then press ENTER:
dskcache +p c:
The following information is displayed for drive C:
Disk device :
\\?\\
<SCSI DEVICE ID
>
Current Settings :
Write Cache is enabled
Power Protect is disabled
New Settings :
Write Cache is enabled
Power Protect is enabled
Note
You can turn on the Power Protect write cache option only for disks that are currently present on your computer. By default, the Power Protect option is turned off. As a result, this option is turned off for any hard disks that are added to the computer after you apply this setting. When you add additional hard disks, you must turn on the Power Protect option for those disks if you want the setting to apply to those disks.
Step 2. Configure registry subkeys
You must also configure the following registry subkeys on the Terminal server and on all file servers:
