When attempting to access the page locally, such as http://<servername>/FSAReporting/FSAReporting.asmx on the EV server, the following is seen: 

Server Error in '/FSAReporting' Application.

Request format is unrecognized

Cause

This issue is caused if the Documentation attribute is not being added under protocols in the web.config file. 

Solution

Modify the web.config file to add the Documentation attribute.  

1. On the Enterprise Vault (EV) server, open Notepad as Administrator.
2. Select File > Open and select <Install_path>\Enterprise Vault\FSAReporting\web.config file. 
3. Modify the following section:

 <protocols>
         <remove name="Documentation" /> 

TO: 
 
 <protocols>
         <add name="Documentation" /> 

4. Save the file and perform an iisreset on the EV server. 

The 1309 event ID should no longer occur and the http://<servername>/FSAReporting/FSAReporting.asmx page should open properly on the EV server.
