Unable to see all user protocols when in Administrator mode

Hello,

Is there a reason why I can't see a certain user's protocols in the Network Navigator pane even though I'm in the "Enable as Administrator" mode.

For a certain user account I only see a limited number of the protocols that I would expect to see. Is this something to do with version control or some permissions setting? ... or maybe protocols being created in one version of the server application having been moved to a later version?

Thanks for any advice.
