This time, I want to discuss on an error occurred when users want to access Citrix Web Interface. This may happen for new farms or when new XML servers added to the farm. 



Issues :

• Users received below error when accessing Citrix Web Interface :
  

Troubleshooting 

1. From Citrix Web Interface server, go to application log, and search for Event ID 31003 and Event ID 30110.
2. Those Event IDs indicates that XML service transition failed.

4. Set the name as UseNetworkLogon
   
   
   
   
   
   
   
5. Right-click at the newly created key, and click Modify...
   
   
   
6. Change the value data to 1. Ensure the base is Hexadecimal.
