Server Web Adaptor
ArcGIS Web Adaptor allows ArcGIS Server to integrate with your existing web server. It is compatible with IIS and runs in your existing website to forward requests to your ArcGIS Server machines.
A myriad of benefits are available to you by using a web adaptor, with a significant one being the ability to expose your ArcGIS server through your organization's standard website and port. Refer to Esri’s Use ArcGIS Web Adaptor article for more information.
If you won’t be installing Web Adaptor, refer to Esri’s Configure a secure environment for ArcGIS Server article for information on securing ArcGIS Server without a web adaptor.
The following is a list of items to take into account:
- Be aware that the installation checks for the existence of certain IIS components. Refer to Esri’s Automatically enable IIS components article for more information. You can either allow the installation to automatically enable the required components or manually enable them. Esri’s Manually enable IIS components article shows you the steps for Windows Server 2016, 2019, 2022, and 2025.
- Decide which type of server certificate you are going to use for creating an HTTPS connection between Web Adaptor and your server. If you opt for a CA-signed certificate, it might necessitate a conversation with your IT department because they need to bind the certificate to port 443.
- Select a website for the adaptor, but if you aren't prompted to select a port, then you have only one website. Therefore, Web Adaptor is automatically placed on that one.
