CRM 2011 and Reporting Services "ArgumentNullException: Value cannot be null.

Problem
In CRM 2011 trying to run a report you get an error that says "invalid argument" (may be different). In the event viewer you see the error "ArgumentNullException: Value cannot be null", mine says "name cannot be null"

Solution
1. On the CRM server open up the Windows Firewall
2. Look for the inbound rule for the Local Port 808
3. Enable this rule
