Go to Start > Programs > ArcGIS > License Manager > Display Hardware Key Status.
The hardware key dialog should state that your Sentinel Driver is installed and running. An 8-digit ESRI_SENTINEL_KEY number is displayed (eg. 37123984). This number is the same number that is on the ESRI Sentinel Key that is plugged into the back of your license server. For the license manager to function, this number must match the number in your license file.
Click OK to close this dialog.
If the correct hardware key number is not displayed or you receive other errors, please follow the steps below.
If a Command Prompt window appears with the message:
The SuperPro driver appears to be installed and running.
However, the hardware key does not appear to be plugged
into a parallel port on this system.
Press any key to continue . . .
Try these solutions:
Verify the key is plugged securely into the back of the server and remove any devices (Zip drive, printer, other Sentinel Keys, etc.) plugged into the back of the ESRI Sentinel Key. After removing these devices, recheck the ESRI Sentinel Key status to see if the key is now recognized.
If multiple hardware keys are plugged into the parallel port, try placing the ESRI Sentinel Key as the first in the chain and recheck the ESRI Sentinel Key status.
If a printer is plugged into the back of the ESRI Sentinel Key, turn the printer on and recheck the ESRI Sentinel Key status.
If there are no devices attached to the ESRI Sentinel Key and the Display Hardware Key Status window still does not return the ESRI Sentinel Key number and driver version, try setting up a printer and printing through the parallel port without the ESRI Sentinel Key attached. If you cannot print, then the parallel port is defective or not configured correctly. See your System Administrator for help on correcting the parallel port communication.
Install the License Manager on another NT system. Once the license manager has been installed, run Display Hardware Key Status; is the correct ESRI Sentinel Key number displayed? If the ESRI Sentinel Key is not displayed, the key may be defective.
If you receive the following message when you Display Hardware Key status:
The SuperPro driver is either not installed on this system or this machine has not been rebooted since it was installed. If the installation of ArcGIS was successfully installed by a user with administrative privileges, you must reboot in order for the Sentinel driver to become active.
Try these solutions:
ArcInfo 8.0+ uses the latest Sentinel Key Driver, version PD 5.38. If you are using ArcInfo 7.2.1 or 7.1x, download and install the latest sentinel driver.
If the Sentinel Driver is version PD 5.38 or later and the ESRI Sentinel Key is conflicting with another device, one option is to install a second parallel port card to add a second parallel port.
Install the License Manager on another NT system. Once the license manager has been installed, run Display Hardware Key Status; is the correct ESRI Sentinel Key number displayed? If the ESRI Sentinel Key is not displayed, the key may be defective.
If you need to order a replacement hardware key contact ESRI Customer Service. When you receive your new key, you will also need to contact ESRI Customer Service for a new license file based on the new Sentinel Key number.
