Additional Notes

• Make sure the new ports you assign do not conflict with other services on your server.
• After changing ports, you may need to update firewall rules to allow traffic on the new ports.
• Always back up your configuration files and registry settings before making changes.

Troubleshooting

If you encounter any issues after changing the ports, verify the following:

1. DNS Resolution: Ensure the server's hostname resolves correctly.
2. Firewall Settings: Check that the new ports are allowed through the firewall.
3. Service Status: Ensure that the services have restarted correctly and are running.
