How do these people get jobs?
Although I don't work in I.T as such, I have to deal with a lot of the clients I.T people some of which are less than impressive.
The I.T girl sent me the following configuration for a new printer, I always ask for the info to be sent in an e-mail so I'm sure it's correct and so that I can blame someone else if it's not,

Hi Mick,

As per our conversation, pls find below the details:

ip: 172.016.067.155
gate: 255.255.255.0
subnet: 172.016.067.155

I reply to her mail asking her to re-confirm the details as it appears she has made a typo*, within 5 mins she was on the phone asking me to point out her mistake as she can't see one!

This should have been blatantly obvious to any one with a basic knowledge of TCP/IP.
