JSI Tip 6871. What ports are used by Windows Product Activation?

Windows Product Activation (WPA) uses the following ports:

PORT    Usage
80      for HTTP
443     for HTTPS
To test if port 80 is open:

1. Start Internet Explorer.

2. Type the following into the address bar and press Enter:

http://www.jsiinc.com:80

3. If my home page opens in the browser, port 80 is open. If the connection timed out, traffic through port 80 may be blocked.

To test if port 443 is open:

1. Start Internet Explorer.

2. Type the following into the address bar and press Enter:

https://www.microsoft.com:443

3. If the Microsoft page opens in the browser, port 443 is open. If the connection timed out, traffic through port 443 may be blocked.

NOTE: WPA will issue Error 32777 if it can't connect to the Product Activation server.

NOTE: WPA will issue Error 32777 if you computer's date or time is incorrect.
