What should I do if the Revit application workstation is unable to connect to Revit Server?

If you find that Revit is unable to connect to Revit Server (via the Manage Connection to Revit Server Accelerator dialog, in the case of a server with the accelerator role enabled, or via file navigation, in the case of a server with the host role enabled), do the following:

1. In your Windows Server manager, verify that all Revit Server role and role service prerequisites are properly installed.
2. In your IIS manager,verify that the Revit Server Application Pool is running.
3. Verify that your internet security applications (such as a firewall) are configured to allow Revit Server traffic to pass.

If you are still unsuccessful, in IIS Manager expand the Default Web Site and select the model service or the local service. Switch to content view, right click on any of the *.svc files, and select Browse.

Your browser will be invoked, and if you see the error "Handler 'svc-Integrated' has a bad module 'ManagedPipelineHandle'" in its module list," you will need to repair your .NET installation through the control panel.

This condition is most frequently encountered when system prerequisites were not correctly configured prior to installing Revit Server. Following reboot, Revit Server will function correctly.
