If you don't see any useful error logs, here's a few more points and questions you might want to answer before opening a support case:
- Does the error occur for other shortcuts, or only this particular one?
- Can the error be reproduced from other laptops / computers?
- Can you access the shortcuts with full named users?
- Check the security rights for both the shortcut itself and the original location of the shortcut (where the shortcut is pointing to).
- Check that all the services are running properly.
I would suspect it has something to do with the security settings for that user / entry access rights of the folders. Try reading the thread below. Basically, check to see if that read only user belongs to a group that doesn't have the browse/view security rights.
