I'm stood in front of a Mitel 5000 that this client has bought from another company down the road. I have no idea of the username or password though.
Can i reset this through the screen on the front or some other way?

Yes.... and no.
Through the front panel you can completely default the database, this will clear out all passwords and users except the default, but it will also completely wipe out the database (and possibly the license key, I don't remember for sure but I do have a test system should this become a need to know).
Otherwise, the only option is having tech support clear the password for you and this requires a USB connection as well if I remember correctly.
EDIT: I see in the manual it talks about resetting the admin password through the front panel, but I don't see that option anywhere, will do some checking.
EDIT2: Yeah, nevermind... Their solution is to default the system database and then restore a database with a known or no password. Otherwise it is standard Mitel procedure, get AMC record moved to your account, then fill out the paperwork for password reset and pay a TSI credit to get tech support to reset it.
