When Accessing Recovery Manager Web Portal Remotely and Entering Credentials, Access is Denied (4303818)

There are multiple causes for this issue, all stemming from IIS or Internet Explorer Security settings. Remote authentication utilizes Windows authentication between intranet and internet zones. 

These criteria must be met:

1. The Recovery Manager page URL must be added as a Local Intranet Site.
   
2. Enhanced Protection is recommended to be turned off in Internet Explorer. If not, a combination of security settings must be used to allow Windows Authentication on Intranet Sites.
   
3. Windows Authentication must be Enabled in IIS on the site's Authentication properties.
   
4. In the Providers area in the Windows Authentication properties on the site within IIS, NTLM must be above Negotiate.
