It is not a good practice to store Profiles locally on a Terminal Server - just because if the server dies all the data of your users is gone (unless you made a backup :-) ). However, if you have to have it you might sometimes notice that the disc space on your TS Box looses space faster than expected. When you do some research you find out that mysterious WER folder, which might contain hundreds of MB's in your users (each of them) folders. This WER folder is the place:
C:\Users\%username%\AppData\Local\Microsoft\Windows\WER
where the Windows Error Resporting information is stored. Unless you can start something with that you don't need that folder or the information in it. It's the folder where all the application crash information is stored for a particular user.

To Disable Windows Error Reporting by Using Group Policy
- As needed, see Appendix B: Resources for Learning About Group Policy for Windows Vista, and then edit an appropriate GPO.
- Expand Computer Configuration, expand Administrative Templates, expand System, expand Internet Communication Management, and then click Internet Communication settings.
- In the details pane, double-click Turn off Windows Error Reporting, and then click Enabled.
If you enable this setting, the user can still click Problem Reports and Solutions in Control Panel, but a pop-up message appears, saying that Windows problem reporting has been turned off.
