So if you're still wondering how to change this name (sigh), you can adjust it to read anything you like... just be careful that you do not have two names in any two machines that are the same and have the same model loaded at the same time (this really jacks up how Revit 2011 worksharing works and will cause some dumb stuff...)
So if you have a bunch (or just one) public walk-up or training machines that people use to access workshared Revit 2011 models, enter a name in the user name field that is descriptive as to the machine's use or location:
- San Francisco Giants 2010 World Series Champion Test Machine #1
- Training #1
- 197th Floor Spaceship Walk-up
- Etc.
