# Disable DNS rebind pop-up

The Trust1Connector by default will check and see if a DNS rebind issue has been detected or not.

If this is the case it will try to add a line to the `host`file. This file requires administrative rights to update so a pop-up will appear.

This will look like the following in windows.

If you want to prevent this from happening you can update the Registry key to disable this

The following table indicates which key must be updated with which value
