That is actually far more common than you might expect. We IT folks know the difference between network cables, local intranet, public internet, etc. To many users, "internet" is not even the same concept as we know it at all. They view EVERYTHING that comes into their desktop via the blue cable (or wifi for sophisticated laptop users) as "internet". Their "internet" starts where the blue cable plugs in.
Apologies if I've posted this before, but my all time favourite is the employee who was having trouble connecting to my application. (Hence passed up the tree to me.)
Further conversation revealed that he was unable to log on to the desktop computer at all.
Since I couldn't see that computer ID on the network, I asked him to double check the 'blue cable' and wriggle the plugs at the computer and where it plugs into the wall...
"Uhm, there isn't a blue cable..."
It turned out that he'd found an old computer in a cupboard, plonked it onto a spare desk, and connected up the power cords. Pretty good initiative, but stuck from there.
Unfortunately, at that point I had to refer him back to his local IT support because:
1) There was no way for me to get him an ethernet cable.
2) There was no ethernet port in the room with the desk.
3) The PC would not be allowed to connect to the network
(There is an automatic policy that bans PCs from connecting to the network if they haven't connected for a period of time and I didn't have access to the tool that adds PCs to that list, or the ability to re-build the PC's OS and software to put it into a condition where we'd allow it back onto the network list.)
Noting that the user didn't realise that a desktop computer needed a network cable, imagine how difficult it was for me to explain the above.
In hindsight, I don't blame the help desk for passing the caller to me, because the user had called in with:
"I'm having trouble connecting to [Application Name]"
And they had checked to ensure that he was a member of an appropriate AD group, and had an active account on my system.
From the user's point of view, that was his problem, because he was in goal mode, i.e. "I need another computer that can access [Application] and it would be very handy if it was in this room."
