A couple of random notes from my work notebook (#2 is net/sysadmin/programmer specific):

1) The initial report is always wrong.

2) The problem might not be name resolution, but it's a good place to look first.

3) There's nothing more permanent that a "temporary" solution.

4) Grownups don't like surprises, even if it is their birthday. Don't
surprise your boss.

5) There's nothing like having a process, even if it's just so you know what you're deviating from.
