SYMPTOMS
After a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based computer that is running Terminal Services is configured to use mandatory user profiles and folder redirection, folder redirection works as expected for the first user who logs on to the remote computer. However, later users experience an 11-second delay in folder redirection for each folder.

<div class="cause_section">

CAUSE
This problem occurs because the folder redirection process updates or verifies the client-side caching checksum on the current user's registry when the user logs on to the computer. However, because of the mandatory profile, the checksum changes are not saved in the user's registry. Therefore, the folder redirection code path must time out and regenerate the checksum every time.

<div class="workaround_section">

WORKAROUND
To work around this problem, do not change the user profile to a mandatory profile for the first time that the user logs on to the computer. When the profile is used the first time, the folder redirection updates the client-side caching checksum to the current user's registry only for that time, and the changes are saved permanently. After the user logs off for the first time, you can change the user profile to a mandatory profile. The next time that the profile is used, the registry changes do not occur. Therefore, the delay in folder redirection does not occur when other users log on to the computer.

<div class="status_section">

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was first corrected in Windows Server 2003 Service Pack 2.

Technical support for x64-based versions of Microsoft Windows
Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
