Hello,
I don't have the same Citrix server environment as you. But I can provide with some general troubleshooting steps:
- Verify that the variables are correctly set in the Active Directory and that they resolve to the correct path for the user's roaming profile. Ensure the path to the roaming profile is available and correct from both the Citrix environment and the Application Server.
- Make sure that the user has the necessary permissions to their roaming profile folder. Even though you can access it with your permissions, the user's permissions might be different. Besides, check any Group Policies that may be affecting the roaming profile settings.
- Verify that there are no network connectivity problems between the client, domain controller, and the server where the profile is stored. Besides, check the server resources. If the server is under heavy load or has other resource issues, it might not be able to load the profile.
- The 1521 event code indicates an issue with loading the roaming profile. Look at the Event Viewer on the server for any related errors.
If the issue persists, you might consider reaching out to Citrix support for more specialized assistance.
Best regards
