Today Dave noticed on the CDS Overview medm that the Slow Controls computer froze at EX (h1ecatx1); basically, on the CDS Overview the Slow Controls channels (bottom left of window) were WHITE/INVALID for EX.  

Sheila showed me how to remotely access the Desktop to this computer via a shortcut on the Ops Workstation (basically go to Applications icon/CDS/Remote Desktop/h1ecatx1).  Click the mouse on the desktop and then a remote desktop will open.  On here, the Windows PowerShell window was displaying Errors.  I typed in "exit" and waited many minutes but it did not exit.  I couldn't find "Task Manager" on the PC, so Sheila showed me how to search for it and bring that up.  We selected the Windows PowerShell task & clicked End Task (closing the PowerShell window).  Then the "Restart" icon was clicked to restart the computer (this closes the Remote Desktop session).

At this point, I closed the CDS Overview window (since the EX Slow Controls section was WHITE-box-ed).  Upon re-opening, we were back to having live & GREEN channels for EX.
