# Forcibly Revoke Licenses for Inaccessible Clients

If a client machine becomes inaccessible, you can revoke a license on it either by using the Knowledge Discovery Admin interface, or by sending the `AdminRevokeLicense` action to the License Server.

To revoke a license by using Knowledge Discovery Admin

1. Open Knowledge Discovery Admin for your License Server.
2. In the Control menu, click Licenses.
3. Click the Seats tab.

4. Click the garbage can next to the component whose license you want to revoke.

   The Revoke License dialog box opens.

5. Click Revoke License to revoke the license and free up the seat that the component was using. If a component is running when you revoke the license, it will stop.

   You can view the progress of the action in the Recent Tasks panel.

To revoke a license by sending the AdminRevokeLicense action

- Send the AdminRevokeLicense action to the License Server. This action frees the license from the inaccessible machine.

      http://LicenseServerHost:Port/action=AdminRevokeLicense&ClientProductType=productType&ClientIP=clientHost&ClientServicePort=clientPort

  where,

  `productType` | is the product type of the Knowledge Discovery component whose license you want to revoke.
  `clientHost` | is the IP address of the inaccessible client machine.
  `clientPort` | is the port by which service actions are sent to the component on the inaccessible client (specified by the `ServicePort` parameter in the `[Service]` section of the component configuration file).

  NOTE: Call the AdminRevokeLicense function only for inaccessible client machines. Otherwise, the module shuts down and becomes inaccessible.
