Configure a Subdomain in IIS on Windows Server

Take note and ensure that: 

• The domain name's DNS is hosted through our platform as guided here: Manage DNS via client area 
• You have set up the correct DNS pointing.
• Kindly note that the subdomain will resolve via the HostAfrica DNS, not your Windows DNS Manager.

1. Open IIS Manager on the Windows Server.
2. In the left panel, right-click Sites > choose Add Website.
3. Fill in the form:
   • Site Name: e.g., sub.example.com
   • Physical Path: Browse to (or create) the folder where the site files will be stored (e.g., C:\inetpub\sub)
   • Binding Type: http

   • Port: 80
   • Host Name: Enter sub.example.com(here they put the subdomain name)

Make sure that port 80 (HTTP) and 443 (HTTPS) are allowed through Windows Defender Firewall and any network firewalls.
