DQed on the effect of a disqualification order

When a court orders disqualification, the court obviously has authority to enjoin the attorney or law firm from appearing before the court on behalf of a party.  It is also fairly uncontroversial that the court’s authority extends to so-called ancillary proceedings, such as depositions, in the same matter (even if the judge is not physically present).  But does this disqualification authority extend to bar the lawyer from, for example, counseling (but not appearing for) the client?  I would think so, but apparently there are differences of opinion on this.  DQed has a short comment on the issue here.
