KB439522: “Incorrect server name.” error message displayed when attempting to connect to project source using integrated authentication (Kerberos) in MicroStrategy Developer 10.4

PREREQUISITES
Make sure the intelligence server has already been configured for Kerberos authentication according to the steps from KB19110:
https://community.strategy.com/article/KB19110-How-to-configure-MicroStrategy-Intelligence-Server
SYMPTOM
When attempting to connect to a 3-tier project source using integrated authentication (Kerberos) in Strategy Developer 10.4, the error message below is displayed, even if the Server name field is filled properly:

CAUSE
This is working as designed in Strategy Developer 10.4. The issue occurs because the server name provided is invalid or is not recognized in the network.
ACTION
Below there are a few settings that can be critical for integrated authentication to work properly:
 

1. Open Strategy Developer; 
2. Right click the desired project source and select “Modify Project Source”;​

       3.​ Click on the “Advanced” tab and make sure “Use Integrated Authentication” option is selected;

       4. Click on the “Connection” tab and make sure the “Server name” field is filled properly. In the example, assume the intelligence server’s hostname is “iservername” and the AD domain is “mydomain.com”. Also, verify that the “Port number” field value matches with intelligence server’s port number.

If the steps above were reproduced and the same error still occurs, it’s possible that the intelligence server’s hostname is not recognized in the network. To fix it, follow the instructions below for Windows hosts file configuration:
 

1. In Windows Explorer, access C:\Windows\System32\drivers\etc
2. Use a text editor to open the hosts file;
3. Include a new row following the syntax “ipaddress       hostname          hostname.domain”, like the example below:  

192.168.1.99       iservername       iservername.mydomain.com
