User keeps getting logged out

I have a user who is essentially never able to log in, they are always forced to reset their password. The password reset utility usually also results in locking out the account rather than getting into the account.

I generally end up resetting their password every time they need to log in or publishing their content for them.

Any ideas on how 2 users on the same network can function so differently?
