Port numbers used by Windows Update process
Posted on 2004-03-24
My servers, one win 2K and the other win 2K3 server, both are behind a firewall machine, running web applications. At the firewall, only the essential ports for web site access (eg, ports 80, 8080 and 9080) are allowed to those two servers. Now, I can not run windows updater on any of those servers. Can do it on the firewall machine allright. So, it looks like the firewall has to allow certain port(s) to those two servers. Can you please tell me what are those port numbers are? Thank you.
