Optional LCSCmd.exe Parameters for Domain Controller and Global Catalog Server Discovery

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

If you specify the optional LCSCmd.exe parameters described in this section at any time during deployment, continue to specify the parameters (and the same parameter values) for subsequent actions.

Parameter	Description
/PDCRequired	Specifies whether the primary domain controllers are required for the action. If not specified, TRUE is used. You can set this parameter to FALSE if the primary domain controllers (in the current/specified domain and the root domain) are unavailable or if network connectivity to the primary domain controllers is poor. For most network issues, /PDCRequired:FALSE is the only parameter you will need to use. The other parameters in this table, used to specify a specific domain controller or global catalog server, are optional.
/GC	Specifies the FQDN of the global catalog server that you want to use. You must also specify /PDCRequired:FALSE to override automatic discovery of a global catalog server.
/DC	Specifies the FQDN of a domain controller in the domain where Office Communications Servers reside. You must also specify /PDCRequired:FALSE to override automatic discovery of the primary domain controller.
/RootDC	Specifies the FQDN of a domain controller in the root domain. You must also specify /PDCRequired:FALSE to override automatic discovery of the primary domain controller in the root domain.
/GroupDomainDC	Specifies the FQDN of a domain controller in the domain where Office Communications Server universal groups are located. You must also specify /PDCRequired:FALSE to override automatic discovery of the primary domain controller.
