This video discusses configuration of Administrator computer client options to control which users are displayed.
This mis-configuration can be carried in to the client via scripting or policy and it was initially intended to aid in the speed of loading the client, but it may cause confusion for administrators expecting to see all users that the administrator should have control over.
To resolve this, on the affected client open up the registry editor to:
Set the LoadAdministeredUsers DWORD value from 0 to 1.
And that's it, once you reload the FaxUtil client with the administrator account, you will see all administered users.
As always if you have any questions about this topic or any topic in the world of faxing let us know at The Fax Guys, we are always happy to help.
