> Dear Colleagues: We have a problem with our LC/MS QE instrument. Long ago
we had a problem with it in which every Thursday morning at the same time the
instrument would quit because of some glitch with the internet connection. We
concluded that a strange signal from the internet was causing the instrument to
quit. We implemented a work-around in which the internet connection was
disabled for the time around when this was happening, and the connection was
re-established after the elapsed time. This work-around worked for a long time
with occasional instances at other times when the problem would sporadically
pop-up. The situation has recently changed. The hiccup is now occurring
frequently. It has recently occurred 10 times in 4 days. The error messages
that are reported are copied below. Of course we have been run touch with
Thermo people, but so far the problem has not been solved. Any and all advice
about this will be greatly appreciated.

Sometimes it occurs shortly after setting a worklist running, and last weekend
it ran uninterrupted from Friday until sometime on Sunday when it quit.
Attached below is the error message that appears when the problems occurs. We
don’t know what t o do next, Can you help us? Before we request a visit from
a service engineer I thought a ZOOM or WEbEX “meeting” might be the next thing
to try.

Not sure how to do this. Maybe Boston has some ideas.
