How to change the domain controller and the global catalog server in Cisco Unity 4.x with Exchange 2000 or 2003

Resolution

Change the Domain Controller (Cisco Unity 4.0(4) and Later)

In Cisco Unity 4.0(4) and later, you no longer need to manually change the domain controller that Cisco Unity monitors for directory updates. If a domain controller (DC) stops functioning, Cisco Unity automatically finds another one and resynchronizes the MSDE 2000 or SQL Server 2000 database on the Cisco Unity server with the directory on the new DC.

However, if the current DC is being decommissioned, is malfunctioning, is being rebuilt, or will be off-line for maintenance, you can use the DC/global catalog (GC) Reconnect Settings tool to:

  • Specify the DC that Cisco Unity automatically switches to when the current DC is taken off-line.

  • Schedule the resynchronization of the Cisco Unity database with the Active Directory database on the new DC.

  • Manually change the DC that Cisco Unity monitors before the current DC is taken off-line.

Refer to the Changing the Domain Controller That Cisco Unity Monitors section of Changing the Domain Controller and Global Catalog Server (Exchange 2003 and Exchange 2000 Only) for more information.

Change the Global Catalog Server (Cisco Unity 4.0(4) and Later)

In Cisco Unity 4.0(4) and later, you no longer need to manually change the global catalog server that Cisco Unity monitors for directory updates. If a global catalog (GC) server stops functioning, Cisco Unity automatically finds another one and resynchronizes the MSDE 2000 or SQL Server 2000 database on the Cisco Unity server with the directory on the new GC.

However, if the current GC is being decommissioned, is malfunctioning, is being rebuilt, or will be off-line for maintenance, you can use the DC/GC Reconnect Settings tool to:

  • Specify the GC that Cisco Unity automatically switches to when the current GC is taken off-line.

  • Schedule the resynchronization of the Cisco Unity database with the Active Directory database on the new GC.

  • Manually change the GC that Cisco Unity monitors before the current GC is taken off-line.

Refer to the Changing the Global Catalog Server That Cisco Unity Monitors for Directory Updates section of Changing the Domain Controller and Global Catalog Server (Exchange 2003 and Exchange 2000 Only) for more information.
