SYMPTOMS
When you disable the "Automatically detect slow connections" policy with
the System Policy Editor tool, the Windows NT-based computer on which the
policy is applied may continue to detect slow connections.
CAUSE
This behavior can occur because of an error in the Winnt.adm file that is
used by System Policy Editor.
RESOLUTION
To work around this issue, follow these steps:
- Use any text editor (such as Notepad) to open the Winnt.adm file that
is used by System Policy Editor. This file is typically
located in the %SystemRoot%\inf folder.
- Locate the following section in the Winnt.adm file:
POLICY !!EnableSlowLinkDetect<BR/>
VALUENAME "SlowLinkDetectEnabled"<BR/>
END POLICY
- Modify this section to contain the following lines:
POLICY !!EnableSlowLinkDetect<BR/>
VALUENAME "SlowLinkDetectEnabled"<BR/>
VALUEON NUMERIC 1<BR/>
VALUEOFF NUMERIC 0<BR/>
END POLICY
- Save the Winnt.adm file, quit the text editor, and then restart
System Policy Editor.
- Configure the policy, and then reapply the policy.
STATUS
Microsoft is researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.
MORE INFORMATION
The following registry value determines the status of slow link detection:
Hkey_Local_Machine\Software\Microsoft\Windows NT\
CurrentVersion\Winlogon\SlowLinkDetectEnabled
If the value data of this entry is 1 (enabled), users can choose between
a local or a server-based user profile when a slow network connection is
detected.
When you enable the "Automatically detect slow connections" policy using
System Policy Editor, the SlowLinkDetectEnabled value is added to the
registry and the value data is set to 1 (enabled). When you disable this
entry in System Policy Editor, the SlowLinkDetectEnabled value is removed
from the registry. This causes the value data to return to the default
value of 1 (enabled).
You can use the modified Winnt.adm file to disable the "Automatically
detect slow connections" policy with System Policy Editor. When you apply
this policy, the SlowLinkDetectEnabled value is placed in the registry and
the value data is set to 0 (disabled).
