# Remove a Child Server from the Distributed Action Handler

You can remove a distribution child server from the DAH when the DAH is running either as a stand-alone DAH, or a DAH in a unified Knowledge Discovery configuration. The procedure is different for each case.

To remove a distribution child server from a stand-alone DAH

1. Open the DAH configuration file in a text editor.

2. Find the `[DistributedEnginesN]` section for the distribution child server that you no longer require, and delete it.

3. In the `[Server]` section, decrease the DistributedEngines parameter setting by one.

4. Make sure that the remaining `[DistributedEnginesN]` sections (which list the remaining child servers) are listed consecutively, starting from 0 (zero).

5. Save and close the configuration file.

6. Restart the DAH for your changes to take effect.

To remove a distribution child server from an integrated DAH in which DAH and DIH are configured together

1. Open the DAH configuration file in a text editor.

2. Find the `[IDOLServerN]` section for the distribution child server that you no longer require, and delete it.

3. In the `[DistributionIDOLServers]` section, decrease the Number parameter by one.

4. Make sure that the remaining `[IDOLServerN]` sections (which list the remaining child servers) are listed consecutively, starting from 0 (zero).

5. Save and close the configuration file.

6. Restart the DAH for your changes to take effect.

To remove a distribution child server from an integrated DAH in which DAH and DIH are configured separately

1. Open the DAH configuration file in a text editor.

2. Find the `[DAHEngineN]` section for the distribution child server that you no longer require, and delete it.

3. In the `[DAHEngines]` section, decrease the Number parameter by one.

4. Make sure the remaining `[DAHEngineN]` sections (which list the remaining child servers) are listed consecutively, starting from 0 (zero).

5. Save and close the configuration file.

6. Restart the DAH for your changes to take effect.
