Chemstation error logging

[MX304]

Anyone on here an expert on the Chemstation error logging macros? I have multiple instruments with Chemstation suddenly hanging / crashing on a nightly basis. This has happened out of the blue and I have made no changes to those instruments. I believe it has to do with networking issues causing a momentary loss of communication between the GC/MS and the PC. I am trying to prove that theory to our IT group.

One thing worth checking is the Windows event viewer (outside chemstation, somewhere in the windows control panel). I had a situation a year or two back where one instrument started crashing in the middle of the night, and it was always within 1 minute of a McAffee event, signalling that the virus checking software was updating its virus directory...
It took quite a bit of deduction from file-times of LC-MS data-files and the amount of data they contained to pin down the correlation, but once I'd got it, it was undisputable. We now hide this instrument behind another networked PC, with the other PC doing all the virus checking and being hit by the IT department's updates. So far as possible, the instrument lives in its own private world. Everyone has been happy since...

That was actually the first place I looked, but there is nothing conclusive.
