I am facing an issue with Microsoft Edge. Edge is configured to use system proxy Explicit using PAC file. However every time the internet site is loaded, Edge performs local DNS resolution which fails as our local DNS, Edge should not be performing a DNS resolution in a scenario where the browser is configured to use a proxy server for the target site. Any insight ?

    Hi @dfa dfa ,

    Please consider configuring the proxy settings separately for Microsoft Edge using that PAC file. You can configure the ProxySettings group policy. The value could be:

    SOFTWARE\Policies\Microsoft\Edge\ProxySettings = {
  "ProxyBypassList": "https://www.example1.com,https://www.example2.com,https://internalsite/",
  "ProxyMode": "pac_script",
  "ProxyPacMandatory": false,
  "ProxyPacUrl": "https://internal.site/example.pac",
  "ProxyServer": "123.123.123.123:8080"
}
