Locked out of DEC850. Any means of reseting to factory defaults?

[grimelog]

Can't get in through the gui as a change to a VPN setting locked me out. For the serial console I either have the wrong password, or the fact I disabled root is preventing me from logging in. My main administrator account does not have access through the serial console.

Is there any means of factory resetting the device?

Boot from USB drive and reinstall?

Odd, just had to boot into Windows, and I was able to login.

Wonder if the VPN crashed eventually.
