When opening the GFI MailEssentials configuration, the following error is shown:
'HTTP Error 401.1 - Unauthorized'
- GFI MailEssentials
- All supported environments
Open the GFI MailEssentials switchboard from the Program Start Menu on the server. Make sure that Microsoft IIS mode is enabled. Local mode will only allow access from the server itself.
If Microsoft IIS mode is enabled and you still are unable to access the page, there may be an issue with the authentication configuration in IIS. GFI MailEssentials configuration console is a website hosted by Microsoft IIS, so the site will be subject to whatever security protocols you have in place for your Default Web Site.
Open your Microsoft IIS Manager and check the authentication properties of the GFI MailEssentials website. Make sure that both Windows Authentication and Basic Authentication are selected. If you make any changes here, please open the command prompt and do an IISRESET command so they take effect.
Microsoft IIS authentication is not set correctly which can restrict user's access to the GFI MailEssentials configuration.
