Recast Enterprise Server Troubleshooting
500.21 IIS Error on Server 2008 R2
This is usually caused by the .Net 4.5 Framework being installed before ASP.NET was enabled on the Recast Enterprise Server. To fix it, open Programs and Features and repair .Net 4.5.
Access Denied messages will occur for different reasons depending on if impersonation is used.
This can either be caused by insufficient user permissions or Permissions Checks being disabled in the Recast Control Panel.
This is caused by an untrusted certificate being used on the Recast server. It can be fixed by trusting the certificate on devices that will use the Recast desktop tools.
The invalid URI message occurs when the desktop tools try to connect to the Recast Server with an invalid URI.
