# Remove a child server from the Distributed Index Handler

You can remove a child server from the list of servers to which the DIH can distribute actions.

To remove a child server from the DIH

1. Open the DIH configuration file in a text editor.
2. Find the `[DistributionIDOLServers]` section.

3. Decrease the value of the Number setting by one, and delete the subsection for the child server to remove. Then, if necessary, renumber the individual subsections to restore a consecutive increasing sequence for `N`.

   For example, if the following configuration is your current `[DistributionIDOLServers]` section:

       [DistributionIDOLServers]
       Number=3

       [IDOLServer0]
       Host=emerson
       Port=9100

       [IDOLServer1]
       Host=thoreau
       Port=9100

       [IDOLServer2]
       Host=jefferson
       Port=9100

   This section defines three child servers. To remove the second child server, make the following changes:

   - Decrease Number to `2`.

   - Remove the `[IDOLServer1]` subsection.

   - Rename the `[IDOLServer2]` subsection to `[IDOLServer1]` to preserve the numbering sequence.

   For example:

       [DistributionIDOLServers]
       Number=2

       [IDOLServer0]
       Host=emerson
       Port=9100

       [IDOLServer1]
       Host=jefferson
       Port=9100

4. Save and close the configuration file.

5. Restart the DIH for your changes to take effect.
