When you say "an IT bod at work" is it someone from your actual IT team, or someone you work with who claims to know IT because they installed Linux on a spare PC at home?

AFAIK the who 'wrong password' is a generic thing with Netflix if it doesn't like the device or where you're connecting from (or through). Any other security software on there? Various security software pushes traffic to its own servers/proxies to block/track/monitor what filth is being browsed at home...

Yes, that's what Netflix seem to default to if you do anything they don't like the sound of... but he's already changed the password successfully and spoken to Netflix who can't see anything wrong with the account.

Beany's shout about a new user account is good as that should rule out a corrupt profile/setting/file etc, but this whole thing looks like a policy/rights issue.
