MORE INFORMATION

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
  1. Stop the Terminal Services Session Directory service.
  2. In the registry, locate the following key:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tssdis\Parameters

  3. If the Parameters key does not exist, create it.
  4. Add the following DWORD value:

    TraceOutputMode

  5. Select the option you want:
    • 0 (no output)
    • 1 (output to debugger)
    • 3 (output to log file)
  6. Start the Terminal Services Session Directory service. If you selected option 3 in step 5, Terminal Service Session Directory places the output in a log file that is named Tssdis.log in the System32 folder.
The Terminal Services Session directory log file contains the following entries:
  • Session Directory service started
  • Session Directory service stopped
  • Machine joins session directory
  • Machine leaves session directory
  • User logs in
  • User disconnects
  • User reconnects
  • User logs out
  • Session Directory-related event log messages.
Important If you stop and then restart the Terminal Services Session Directory service, you clear all Terminal Services Session Directory data. Do this only if it is not a problem to do so.
