The problem is only in the field at a few sites.

I do not know when it fails.

It does not happen every time, in fact it may only happen once a week.
Could it be related to the COM server being hit by more than 1 person at a time?
each client machine has it's own COM srever.
Are they running in MTS?
No

Not tried.
The operation that is going on is a credit card operation.
- Swipe card with MSR (COM server)
- Send card information to credit card processing (COM server)
