Troubleshooting: Responder services are blocked because of Esri license expiration messages

By default, 15 days prior to license expiration, Esri will popup a messagebox to warn the user about the impending expiration. This behavior is not good for an unattended backroom server (as your Responder services may be). If you're running the Responder Windows Service the message box may not be displayed, but block the services anyhow. This issue is easily resolved by disabling this timeout message.

Look for AdvancedArcMapSettings.exe, which is installed here: Program Files\ArcGIS\Utilities. This executable cannot be opened using an Esri ArcGIS for Desktop Basic license.

Double-click AdvancedArcMapSettings.exe to open it.
Select the Miscellaneous tab.
Uncheck the License Timeout Warning as shown in the screenshot below.
Click Apply.
Click the red X in the top right corner to close the executable.
If ArcMap was running while you performed this task, restart ArcMap to implement the change.
