TFS 2015 behind a proxy

In many enterprise realities it is quite common that all of the internet access is made via a proxy server. Recently I wrote a post about a Tough life behind a proxy, you may check that for some of my rants and tips. What if your servers do also require internet access? Although it may seem it doesn’t, TFS 2015 has a need to access the web.

What you will need to do is to edit that file and under the section add the following:

Make sure the correct proxyaddress is set and give your TFS main portal page a go. If all went as expected and your settings are valid, you should see the following:


That’s it. It may not be an essential setting, however it is nice to see that there are no errors in the event log and that your users do get a full experience.
