How to set AutoProxy on server core?

Anthony Hunter 11

I need to configure the autoproxy for my server, but I can't find the right command line or reg settings to give my machine internet access on my companies network.
We normally set this through "Internet Options|Local Area Network Settings" on our other machines.

Any help will be appreciated. Thanks!

This is really terrible! coming from a Linux background and facing the harsh reality of using Windows server 2019 core! with 0 good articles about how to get packages installed or even update help to work if your server is behind a corporate proxy, I used all methods the internet has and non of them worked. 0 result! same proxy if I put it on Windows server UI will work without any issue. for one week searched the whole www and tried ALL methods from registery to netsh, to setting env variable, to the method here https://learn.microsoft.com/en-us/answers/questions/703416/proxy-settings-not-working-in-windows-server-core to all methods on github reddit, all fail -- nothing will pass the proxy you can ping proxy, resolve its name, windows tells you it has poxy configured but you cannot reach the internet no matter what you do. ofcourse it not the proxy server issue. its the damn Windows as a shite OS that will enver mature to be a good OS. looks at the command line and config its a nighmare!!! one week of frustration ended up just going for the server with dersktop like a school kid! shame on your MS for not even putting a documentation or addressing this issue!!!!!

I'm observing that netsh winhttp set proxy is ignored on Windows 2022 (Core + Full)

Is there any updated documentation on how one is supposed to configure a system-wide proxy?

Hi everyone!

I encountered exactly the same issue as you: unable to perform updates on Windows Server 2022 Core via a proxy using the command:

netsh winhttp set proxy

After persistent efforts, I finally found:

netsh winhttp set proxy --> is deprecated on Windows Server 2022

You should use the following command:

netsh winhttp set advproxy setting-scope=machine settings-file=settings.json

And the settings.json file should contain:

{ "ProxyIsEnabled": true, "Proxy": "http=http-proxy.com:8080;https=https-proxy.com:8081", "AutoConfigIsEnabled": false, "AutoDetect": true }

There you go! Hoping to have been able to help as many people as possible!

@Julien_31 Thank you! This works for me.

I also need to have some "no proxy" entries; I guessed NoProxy, but it wasn't that. My second guess ProxyBypass worked. Eventually found this documentation

Thanks again for the comment, it allowed me to pick up a task that I had blocked for a few months.

Hi ,

We can use netsh winhttp set proxy to configure the proxy settings for a server core.

Configure your server to use a proxy server:

netsh Winhttp set proxy <servername>:<port number>

For example: netsh winhttp set proxy 10.0.0.6:8080

To reset the winhttp proxy, enter the following command and press Enter:

netsh winhttp reset proxy

For detailed information, please refer to the link below:

Quick Reference for Server Core Tasks

Best Regards,

Candy

That doesn't work, as I need to set the configuration script. Sample url: http://pac.mycompany/mycompany/filtering.pac

This is the setting I need to set:

Hi ,

Please use the following script:

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v AutoConfigURL /t REG_SZ /d "http://pac.mycompany/mycompany/filtering.pac" /f

As the picture below:

To clear that field:

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v AutoConfigURL /t REG_SZ /d "" /f

If you want to use PowerShell, you can run the cmdlet below:

Set-ItemProperty -Path 'HKCU:Software\Microsoft\Windows\CurrentVersion\Internet Settings' -Name AutoConfigURL -Value 'http://www.yourdomain.com/config.pac'

Best Regards,

Candy

Unfortunately still didn't solve my problem. Can't access the internet from my server core machine. Not sure if there is another setting missing.

What's the OS version of your server core? Windows server 2016 or windows server 2019?

Hello,

I am facing the same problem, using Windows Server Core 2019 as well.
"Normal" proxy can be configured via:
netsh winhttp set proxy <proxy>:<port>

Reset with:
netsh winhttp reset proxy

However, when trying to use a .pac file (automatic configuration file), the server seems to ignore the settings.
I have tried setting this via the registry via Group Policy Management Console, same way we do on servers with GUI.
The values are registered in the registry, however they do not seem to have any effect.

Would be nice if someone knows how to make this work.

regards,
Øistein
