How to enable diagnostic debugging for Folder Redirection.

The Folder Redirection extension fdeploy.dll logs events in the Application event log, so that's the first place you should check when trying to troubleshoot a Folder Redirection issue on your system. If that isn't enough however, you can also enable diagnostic logging for this extension by setting the following DWORD registry value to 0x0F:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Diagnostics Set\FdeployDebugLevel

In pre-Vista versions of Windows, doing this will create the diagnostic log file %windir%\Debug\UserMode\fdeploy.log. For Vista however, doing this simply adds more detailed info to the event log.
