Have you been in situations where your users are experiencing performance issues with Dynamics CRM that you cannot replicate?
Not many people know, but Dynamics CRM includes a hidden diagnostics page that enables you to troubleshoot client side issues including network performance issues and web browser compatibility issues.
How Do I Find It?
The diagnostics page is accessible here: http://<YourCRMServer>/tools/diagnostics/diag.aspx
How Does it Work?
When users navigate to the diagnostics page, a series of tests can be executed on the users browser to check for any issues including slow network connectivity and browser performance issues.
