Symptoms

If you have many external trusts and many simultaneous logons where the domain is not specified on a Microsoft Windows 2000 Server-based domain controller, the Local Security Authentication Server (Lsass.exe) process may stop responding.

Note This problem does not apply to any logons where the domain is specified.

Cause

This problem occurs because the Lsass.exe process runs out of resources if the number of simultaneous logons multiplied by the number of trusts is more than 1,000.

This problem typically will not occur. This problem may require hundreds of trusts and dozens of users who attempt simultaneous logons. For example, if the domain controller has 75 external trusts or downlevel trusts and the domain controller experiences 25 simultaneous logons where no domain specified, the number of logons multiplied by the number of trusts is 1,875 (25 logons x 75 trusts = 1,875). In this example, the Lsass.exe process would not be able to allocate enough resources to authenticate the client logon requests.

The problem can also occur more likely when a substantial number of domains are reachable onyl through an unreliable network link or are not reachable at all.

Hotfix installation instructions

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

You must create a new registry subkey to enable the functionality in the hotfix. After you enable the hotfix, the domain controller will no longer try to authenticate a domainless logon by querying external trusts. 

Important This new behavior may cause unwanted side effects if you have clients that do not send domain names with their logon requests. Such clients may include Microsoft Windows 98 clients and Microsoft Outlook Web Access. These programs will still work if the user account is in the Windows 2000 Server domain or in the global catalog. You should only experience problems if a user account is in an external domain.

To create the new registry subkey to enable the hotfix, follow these steps:
  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters .
  3. Right-click this subkey, point to New, click DWORD Value, type NeverPing, and then press ENTER.
  4. Right-click NeverPing, click Modify, type 1 in the Value data box, and then click OK.
  5. Exit Registry Editor.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
