Troubleshooting an IDP Detector Engine Update
In NSM, the default URL from which to obtain updates is https://services.netscreen.com/restricted/sigupdates/nsm-updates/NSM-SecurityUpdateInfo.dat. If you encounter connection errors, ensure this setting has not been inadvertently changed.
To restore the default URL:
Select Tools > Preferences.

Click Restore Defaults.
NSM restores the URL in the Download URL for ScreenOS Devices text box.
Click OK.
