SUMMARY
The Exchange Server 2003 Site Replication Service (SRS) provides mail-based directory replication between Exchange Server 2003 administrative groups and Microsoft Exchange Server 5.5 sites. When you install the first Exchange Server 2003 server in an Exchange Server 5.5 site, SRS is automatically installed. It creates a connection agreement with Active Directory Connector (ADC) and replicates directories based on the connector's schedule. This article describes how to build an SRS when you do not have a backup of the SRS database, Srs.edb.



MORE INFORMATION
If you do not have a backup of the SRS database, you can delete and re-create the service if you have another Exchange Server 2003 server or Exchange 2000 server in the site. If you have not yet installed a second Exchange Server 2003 or Exchange 2000 server, you may install one temporarily and then remove it after the recovery process has completed.

You must have another Exchange Server 2003 or Exchange 2000 server in the site because the last SRS in a site cannot be deleted until all the servers in the site have been upgraded from Exchange Server 5.5 to Exchange Server 2003. This safeguard prevents you from severing the links between Exchange Server 5.5 and the Exchange Server 2003 or Exchange 2000 servers in the site. If you are going to create a new SRS database on a server, you first must remove the existing service completely. When you add a second Exchange Server 2003 or Exchange 2000 server to the site, you can delete any SRS you want if there is more than one SRS in the site.

Note This operation generates approximately as much replication traffic as the traffic that is generated if you install two new Exchange Server 5.5 servers in the site.

To re-create an SRS, follow these steps:
 * 1) Install a second Exchange Server 2003 or Exchange 2000 server in the site, if it is required.
 * 2) Start Exchange System Manager from the first Exchange Server 2003 computer.

Note You cannot run Exchange System Manager remotely when you create a new SRS database. However, you can connect to the server by using a Microsoft Windows Terminal Services session. A Windows Terminal Services session has all the required characteristics of a local console session.
 * 1) Double-click Tools to view the Site Replication Services container.

Note: Each SRS in your organization appears as Microsoft Exchange Site Replication Service . If Directory Replication Service  appears, click Site Replication Service View on the View menu.
 * 1) Click Site Replication Services, click Action, click New, and then click Site Replication Service.

Note: When you create a new SRS, Exchange Server 2003 performs directory updates similar to the updates that are performed when you join a new server to a site. It may take several minutes for the process to complete.
 * 1) Follow the instructions that appear to create the new SRS.
 * 2) You are prompted to enter a password that will be used to run the SRS.

These credentials are loaded from the msexchlegacydomain and msexchlegacyaccount attributes of the Exchange Server administrative group that contains the SRS.
 * 1) If there are multiple Exchange Server 5.5 computers in the site, click the Exchange Server 5.5 server that will be synchronized with the new SRS.

By default, Exchange System Manager auto-selects the second directory service if there is only one other directory service in the administrative group.
 * 1) After the new SRS has been created, delete the original SRS on the first server.

To move the SRS back to its original server, repeat steps two through seven, but reverse the server where each action is performed.

Troubleshooting SRS Creation
When you create the SRS, you may receive following error message:

The server is not operational.

Facility: Win32

ID No: 8007203a

Exchange System Manager

This error message indicates that port 379, the port that is used for SRS LDAP requests, is not responding on the server that the SRS is trying to synchronize with. If the secondary server is trying to synchronize with another SRS service, make sure that the other SRS service has been started. If the secondary server contains the Exchange Server 5.5 directory service, change the Exchange Server 5.5 server's LDAP port 379 and then restart the Msexchangeds service. When you do so, SRS communication is successful. For additional information about how to change the LDAP port number, click the following article number to view the article in the Microsoft Knowledge Base:

When you create the SRS service, you may receive the following error message:

The distinguished name already exists. Try the operation again. If the error recurs, try stopping the directory service and the Administrator program and then restarting them.

ID no: c1030b0c

Exchange System Manager

This error message indicates that communication with the secondary server occurred successfully, however the secondary server's directory database still has a reference for an old SRS object that uses the same name. To resolve this issue, use the Microsoft Exchange Server 5.5 Administrator program on the secondary server to remove this duplicate object. For example, if &quot;Server1&quot; is the name of the server where the new SRS has been installed and &quot;Server2&quot; is the name of the secondary server, use the Exchange Server 5.5 Administrator program to connect to Server2 and to delete the Server1 object from the Servers container. After you do so, use Exchange System Manager on Server1 to re-create the SRS.
