How do I verify network endpoint connectivity.
Hi, Is there an easy way to verify internet endpoint connectivity. I come across this regularly where a product documents that I need to verify internet endpoint connectivity to various url's and ports. For example, for windows update: - this page https://docs.microsoft.com/en-us/windows/deployment/update/windows-update-troubleshooting has this entry - Ensure that devices can reach necessary Windows Update endpoints through the firewall. For example, for Windows 10, version 2004, the following protocols must be able to reach these respective endpoints: Protocol Endpoint URL TLS 1.2 *.prod.do.dsp.mp.microsoft.com HTTP emdl.ws.microsoft.com HTTP *.dl.delivery.mp.microsoft.com HTTP *.windowsupdate.com HTTPS *.delivery.mp.microsoft.com TLS 1.2 *.update.microsoft.com TLS 1.2 tsfe.trafficshaping.dsp.mp.microsoft.com How do I test that. obviously using ICMP is no test for verifying http, https or TLS connectivity. What is the process? I haven't found anything powershell to do it as everything seems to rely on ping. i figure for the standard addresses, I could do something like this for http Telnet address1.microsoft.com 80 but I figure Telnet is old school, there should be something newer around these days and also how do I test the entries with * on the front of the name how do I test TLS 1.2 I'm sure there are hundreds of tech support people out there doing this currently, somebody should be able to point me in the right direction.
