Explicit steps given for reference.
1. Jeff K. noted that the readbacks for the end Y ALS EPICS channels were turning white on the ALS overview screen.
2. The current time for each PLC on h1ecaty1 was still updating on the CDS overview screen (bottom left corner under Slow Controls).
3. I ran rdesktop -T 'h1ecaty1' -g 2048x1280 -x l h1ecaty1 to connect to h1ecaty1 using remote desktop.
4. I logged in as controls.
5. The IOC terminal was minimized. I opened it by clicking its icon on the taskbar (circled in attached screenshot).
6. There were no errors initially shown in the terminal.
7. I hit enter in the terminal. The error shown in the attached screenshot appeared.
8. I hit enter again. No further errors appeared.
9. I restarted the computer by double clicking the icon on the desktop labeled 'RESTART'.
10. The issue was resolved.
The following is a list of commands to connect to various Windows machines using remote desktop:
end X BRS: rdesktop -T 'h1brsex' -g 2048x1280 -x l h1brsex
end Y BRS: rdesktop -T 'h1brsey' -g 2048x1280 -x l h1brsey
corner station Beckhoff: rdesktop -T 'h1ecatc1' -g 2048x1280 -x l h1ecatc1
