Legacy Files (Not Required)

These files are from the original batch-based installer and are not used by the Inno Setup version:

• MA3NetworkConfigv4.bat - Original batch script
• ge_runasuser.exe - Run-as-user utility
• RebootDelay.exe - Reboot delay utility
• $PLUGINSDIR/ - NSIS plugin remnants

Troubleshooting

"Requires administrator privileges"

Right-click the installer and select "Run as administrator"

Network doesn't reconnect after configuration

1. Manually disconnect and reconnect the network adapter
2. Check Windows Services that dot3svc and/or Wlansvc are running
3. Verify the machine has the required certificates

AESFMA wireless doesn't connect

• Verify the FreeRADIUS SSL certificate is installed
• Check that the machine is in the correct AD group
• Ensure the wireless adapter supports WPA2-Enterprise

Wired 802.1x authentication fails

• Verify the machine account is in the correct AD group
• Check that the switch port is configured for 802.1x
• Review the RADIUS server logs for authentication errors

Check installed profiles

Wired profiles:

netsh lan show profiles

Wireless profiles:

netsh wlan show profiles

Remove and reinstall profiles

Remove wired profile:

netsh lan delete profile interface="Ethernet"

Remove wireless profile:

netsh wlan delete profile name="AESFMA"

Then run the installer again.

Building

1. Install Inno Setup 6.x
2. Open MachineAuth.iss
3. Compile (F9)
4. Output: Output/MachineAuthSetup.exe

Technical Notes

• No reboot required
• Brief network interruption during configuration (~10-15 seconds)
• Safe to run multiple times
• Does not remove existing profiles (adds/updates)
