IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows Registry



SYMPTOMS
When you try to enter a very large value for the Slow Network Connection Timeout setting in the Windows NT User Profiles policy while creating or editing a computer policy, you may be unable to enter a value greater than 20,000. This may occur even though the following related registry key has a well-documented range of possible values from 0-120,000 milliseconds:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Currentversion\Winlogon\SlowLinkTimeout

Also, if you edit the Winnt.adm file to specify the correct range of 0-120,000 for this policy, the Poledit user interface may malfunction and display negative values for this parameter when you use the interface controls to enter a value.



CAUSE
This problem can occur by having the maximum entry for the Slow Network Connection Timeout value incorrectly set to 20,000 in the %SystemRoot%\Inf\Winnt.adm file. Also, Poledit.exe only uses 16-bit integers for the minimum and maximum values associated with the numeric interface value entry controls.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem.

To resolve this problem, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:

  Date       Time    Size      File name     Platform -  15/11/99   20:07   123,152   Poledit.exe   Intel 15/11/99  19:38    24,475   Winnt.adm     Intel

15/11/99  20:07   194,320   Poledit.exe   Alpha 15/11/99  19:37    24,475   Winnt.adm     Alpha



WORKAROUND
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To work around this issue, edit the appropriate registry entry. To do so, use Registry Editor to locate the following key in the registry:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Currentversion\Winlogon

Add the following value to this key

Value Name: SlowLinkTimeOut

Data Type: REG_DWORD

Value:.

where  is a numeric value between 0-120,000. Note that the permissible range for this registry entry is from 0-120,000 milliseconds, and the default value for this registry entry is 2,000 milliseconds.



STATUS
Microsoft has confirmed that this is a problem in Windows NT 4.0.
