You may experience slow authentication performance on a Windows Server 2008-based RODC when it is under high load or when the link between the RODC and a writable domain controller is slow

Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows.

Symptoms

Consider the following scenario:

  • You have a Windows Server 2008-based read-only domain controller (RODC) that has the Netlogon chaining feature enabled.

  • The Windows Server 2008-based RODC is under heavy load. Or, the link between the RODC and the hub domain controller is slow.

In this scenario, Authentication and Directory Services are either slow or these services fail on the RODC. Users may also encounter one of the following symptoms:

  • If a user to logs on to the domain through the RODC, the logon may take a long time.

  • The RODC does not reply, or the RODC replies slowly to Lightweight Directory Access Protocol (LDAP) requests or to Kerberos version 5 protocol requests from clients.

Additionally, event ID 1173 is logged many times in the Directory Service event log:Log Name: Directory Service
Source: Microsoft-Windows-ActiveDirectory_DomainService
Event ID: 1173
Task Category: Internal Processing
Level: Warning
Keywords: Classic
Description:
Internal event: Active Directory Domain Services has encountered the following exception and associated parameters.

Exception: e0010004
Parameter: 0

Additional Data

Error value: -1603
Internal ID: 205036b

Cause

This problem occurs because the NetrLogonGetDomainInfo function incorrectly holds some very important sections open when the function performs the chaining call to the writable domain controller. This problem causes a high load on the RODC when the NetLogon chaining feature accesses a slow wide area network (WAN) link.

Workaround

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756 How to back up and restore the registry in WindowsTo work around this problem, disable the Netlogon chaining feature. To do this, follow these steps:

  1. Open Register Editor.

  2. Locate the following registry subkey:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netlogon\Parameters\EnableChainSetClientAttributes

  3. Set the value of the EnableChainSetClientAttributes registry subkey to 0.

Status

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

More Information

In Windows Server 2008, the NetLogon chaining feature enables any client that opens a security channel to the RODC to update the following attributes to the full domain controller through the RODC:

  • operatingSystem

  • operatingSystemVersion

  • operatingSystemServicePack

  • DNSHostname

  • servicePrincipalName
