Problem with Node listings

The first thing I've noticed on your screen shot is that current users name is "alcadmin" (active user name is written in description of LinkServer connection node right after "Servers" node). This is not default admin login name. So. You or somebody else created this new user ("alcadmin"). The set of nodes (on your screen shot) under LinkServer connections node is usual for every new created user with default permissions. Of course the first thing I can suppose that you try to execute functionality without corresponding user permissions. To manage "Users" context (to create new user accounts for instance) user "alcadmin" must have administrator permissions for it. Just open user properties for "alcadmin" and check if he has administrator permissions for "users" context. Pay attention that context mask is exactly "users" but not "users.*". Or you can connect to LinkServer as real admin of your Aggregate Likserver ("admin" by default). But it is a good practice not to use administrator account if it is not inescapable.

I think this documentation links could be useful for you:
