I finally have gone thru the entire network and tested every cable and the register in question now pings w/o errors for 24 hours in my last test. I reattached the Verifone pinpad and we rang up a debit trans which worked. But a bit later, a cash transaction failed with no receipt being printed or generated and the POS application errored and crashed. The trans shows up in the customers history w/o a trans # but when the trans is re-printed nothing is there. This register has run flawlessly for 3 weeks w/ the pinpad enabled and attached to it w/o any debit trans being processed during that time. Now, almost immediately after a debit trans is processed do we see instability.
