Event ID 1023 — TS Session Broker Configuration

Updated: January 5, 2012

Applies To: Windows Server 2008


In Windows Server 2008, Terminal Services Session Broker (TS Session Broker) supports a built-in load balancing functionality and supports configuring multiple IP addresses (including IPv6 addresses) to be used for redirection. Both of these capabilities are supported only by terminal servers running Windows Server 2008.

With TS Session Broker Load Balancing, when a user without an existing session connects to a terminal server in the load-balanced farm, the user will be redirected to the terminal server in the farm with the fewest sessions.

Note:  TS Session Broker was formerly called Terminal Services Session Directory.

Event Details

Product: Windows Operating System
ID: 1023
Source: Microsoft-Windows-TerminalServices-SessionBroker
Version: 6.0
Message: TS Session Broker farm %1 is in an inconsistent state. For TS Session Broker load balancing to work correctly, all terminal servers in the same TS Session Broker farm must either be configured to use TS Session Broker load balancing or to not use TS Session Broker load balancing. Terminal servers that are running Microsoft Windows Server 2003 do not support TS Session Broker load balancing.


Reconfigure TS Session Broker Load Balancing

To resolve this issue, do either of the following:

  • Enable TS Session Broker Load Balancing on all terminal servers in the farm. Note that terminal servers that are running Windows Server 2003 do not support TS Session Broker Load Balancing.
  • Disable TS Session Broker Load Balancing on all terminal servers in the farm.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To configure TS Session Broker Load Balancing:

  1. On the terminal server, open Terminal Services Configuration. To open Terminal Services Configuration, click Start, point to Administrative Tools, point to Terminal Services, and then click Terminal Services Configuration.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  3. Under TS Session Broker, double-click Member of farm in TS Session Broker.
  4. On the TS Session Broker tab, select or clear the Participate in Session Broker Load-Balancing check box.
  5. Click OK to close the Properties dialog box.


To verify that TS Session Broker is working properly:

  1. On the terminal server, start a new Terminal Services session.
  2. After the session is established, disconnect the session.
  3. On a different terminal server, but one that is also a member of the same farm in TS Session Broker, try to reconnect to your existing session. If you are able to reconnect to the existing session, TS Session Broker is working properly.
