256986 Description of the Microsoft Windows Registry



SYMPTOMS
Client Setup may not start on a Windows 2000-based domain controller because the replication of the SMS#_ account creation takes longer than 60 minutes on a large Windows 2000 Active Directory site. The same symptoms occur if the replication for the temporary bootstrap account succeeds in time and the SMS#_ client service account is created.



CAUSE
The SMS#_ account is created by the CCM thread of the SMS Executive service after the thread receives a client configuration request for the target system. The Systems Management Server (SMS) Client Configuration Manager (CCM) Client Bootstrap is started with this account to start the client installation on the domain controller. After startup, the Bootstrap service creates the SMS& account, which is used by the Client service to spawn the client agents in a separate account context.

Both accounts are created only when the SMS client is installed on a domain controller and needs the &quot;Logon as a service,&quot; &quot;Act as part of the operating system,&quot; &quot;Create objects,&quot; &quot;Increase quotas,&quot; and &quot;Shut down system&quot; user rights. These rights are assigned after the account creation. The client code waits a maximum of 60 minutes for the account replication between the primary domain controller (the PDC emulator in Windows 2000 Active Directory) and backup domain controller. Because of the architectural changes in Windows 2000, the replication may take longer than 60 minutes and the client installation may not work on a Windows 2000-based domain controller.



RESOLUTION
To resolve this problem, obtain the latest service pack for Systems Management Server version 2.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Systems Management Server 2.0 Service Pack 3.



MORE INFORMATION
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.

You must configure a time-out value on the primary domain controller (PDC) emulator in Windows 2000 Active Directory because the client installation reads the value directly from the PDC's registry. You need to insert the registry value only on the PDC emulator. To determine which computer is the PDC emulator:
 * 1) Start the Active Directory Users and Computers administrative tool.
 * 2) Right-click the domain, and then click Operations Master.
 * 3) The PDC emulator is listed on the PDC tab under Operations Master.

To configure the time-out value, perform the following steps:  Start Registry Editor (Regedt32.exe) on the PDC emulator only. Locate and click the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Client\Configuration\Domain Controller

 Add the following value :

Value name: Account Synchronization Max Wait (minutes)

Data type: DWORD

Value: 60 is the default; set the value depending on the domain replication interval or use 300 minutes (5 hours) as a start point.
