When performing windows updates on a computer you may run into the following error “Windows Update error code 8024402F” which is caused by network issues.

This issue is caused when the network firewall or computer antivirus is blocking the computer from accessing the IP address associated with the windows update server. 

The reason why your firewall or antivirus may be blocking the IP address is because Microsoft reuses the same IP pools used by Azure. This can cause the IP address to be sometimes associated with Pornography websites or other types of websites that may be blocked by your firewall or antivirus‘ content filter.

Method of finding IP address associated with Windows update server:

Run a packet capture using your Firewall or Wireshark on the computers WIFI or Ethernet NIC card while running the update check and look for the following packet sequence:

x.x.x.x x.x.x.x /get winupdates/……………anything can go here…..

Once you acquire the IP address associated with that packet place it in your firewall’s white-list and you should be able to now grab updates from the windows servers.
