Disable SID filter Quarantining

Updated: October 26, 2012

Applies To: Windows Server 2008, Windows Server 2008 R2

Although it is not recommended, you can use this procedure to disable security identifier (SID) filter quarantining for an external trust with the Netdom.exe tool. You should consider disabling SID filter quarantining only in the following situations:

  • You have an equally high level of confidence in the administrators who have physical access to domain controllers in the trusted domain and the administrators with such access in the trusting domain.

  • You have a strict requirement to assign universal groups to resources in the trusting domain, even when those groups were not created in the trusted domain.

  • Users have been migrated to the trusted domain with their SID histories preserved, and you want to grant those users access to resources in the trusting domain (the former domain of the migrated users) based on the sIDHistory attribute.

For more information about how SID filtering works, see Security Considerations for Trusts (http://go.microsoft.com/fwlink/?LinkID=111846).

You can disable SID filter quarantining by using the Netdom command-line tool. For more information about the Netdom command-line tool, see Netdom Overview (http://go.microsoft.com/fwlink/?LinkId=111537).

Membership in Domain Admins or Enterprise Admins in Active Directory Domain Services (AD DS), or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

  1. Open a Command Prompt.

  2. At the command prompt, type the following command, and then press ENTER:

    Netdom trust <TrustingDomainName> /domain:<TrustedDomainName> /quarantine:No /userD:<DomainAdministratorAcct> /passwordD:<DomainAdminPwd>
    
    noteNote
    You can enable or disable SID filter quarantining only from the trusting side of the trust. If the trust is a two-way trust, you can also disable SID filter quarantining in the trusted domain by using the domain administrator’s credentials for the trusted domain and reversing the <TrustingDomainName> and <TrustedDomainName> values in the command-line syntax.

  1. Open a Command Prompt.

  2. At the command prompt, type the following command, and then press ENTER:

    Netdom trust <TrustingDomainName> /domain:<TrustedDomainName> /enablesidhistory:Yes /userD:<DomainAdministratorAcct> /passwordD:<DomainAdminPwd>
    
    noteNote
    You can enable or disable SID filter quarantining only from the trusting side of the trust. If the trust is a two-way trust, you can also disable SID filter quarantining in the trusted domain by using the domain administrator’s credentials for the trusted domain and reversing the <TrustingDomainName> and <TrustedDomainName> values in the command-line syntax.

The following table describes the placeholder values in the syntax for the netdom command.
