I have solution for this so the simplest solution is connection with "net use x: / d" to separate. But now its own roaming profile on the server which is aware, the separation is not possible. It remains a fact that is the only logging off the workstation and a new application as an administrator. But of course there is also a convenient solution. The server finds fault with the second link structure is not if it is even addressed by name and once by its IP address. The IP address is easily found with a ping.
Now I have two drive letters associated with the same share. On the drive X: with normal user rights, and on Y: the rights of the administrator.
C: \> net use X: \ \ myserver \ test / user: dom \ Worker
C: \> net use Y: \ \ 10.0.0.2 \ test / user: dom \ administrator
