# AdminRevokeLicense

Revoke a license that has been granted by License Server when a license has been issued to a client that no longer exists. You must specify the product type and service port for the service that you want to revoke the license from, by setting ClientProductType and ClientServicePort. You must also set one of ClientIP, ClientHostID, ClientHostName, or ClientMAC to identify the host of the service.

You can use the LicenseInfo action to find details of the licenses that License Server has granted.

NOTE: You must use the `AdminRevokeLicense` action only when the client no longer exists. If the client still exists, you can revoke the license from the machine on which the service is installed by entering the following at the command line:

    <executable_name>.exe -revokelicense

The service must be stopped before you revoke the license.

## Example

    http://123.4.5.67:20000/action=AdminRevokeLicense&ClientProductType=IDOLSERVER&ClientIP=myHost&ClientServicePort=6500

This action revokes the license issued to an IDOL server service. The license was issued to an IDOL server service on the machine with the host name `myHost` that the License Server communicated with using port `6500`.
