1) Config, connections, or whatnot are one-time only. You're not going to screw up many times.
2) Not all WebServices have their own test-server so count yourself lucky if the ones you use have them :)
3) You're testing their code instead of yours if you have to make sure correct data etc comes back.
I usually only write unit-tests if they came back with bad data and we did not anticipate it (edge-case situation).
