I proceeded to go through the rest of the other vendors' computers, fixing them one at a time. When I was done, all of the computers could talk to all of the other computers, which caused the customer to believe that I had been right all along and the other computers had indeed been the broken ones - the ones whose own vendors had been unable to fix. Our company came off looking really good, fixing all the other vendors' computers after the other vendors had been there and simply blamed everybody else (as I too had, originally - but I had been right!).
The customer said to let them know any time I felt like a trip to Jacksonville, they'd be glad to invent a problem and request to have me come down to "fix" it.
