Windows Server 2012 R2 - unable to change the Network category when is in domain

Question

HI, I've read articles about this topic but after all tries - i couldn't find appropriate decision and i still have problem. 
Set-NetConnectionProfile : Unable to set the NetworkCategory due to one of the following possible reasons: not running
PowerShell elevated; the NetworkCategory cannot be changed from 'DomainAuthenticated'; user initiated changes to Networ
kCategory are being prevented due to the Group Policy setting 'Network List Manager Policies'.
At line:1 char:1
+ Set-NetConnectionProfile -InterfaceIndex 16 -NetworkCategory Public
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : PermissionDenied: (MSFT_NetConnect...EA9E84DF602D}"):root/StandardCi...nnectionProfile)
   [Set-NetConnectionProfile], CimException
    + FullyQualifiedErrorId : MI RESULT 2,Set-NetConnectionProfile
I have  two NIC on my server2 - joined to domain as domain member  ( NIC are public (internet) and private (local net) )  Now they both are in NetworkCategory - DomainAuthenticated.
I tryed:
1. Check for Administrator  privileges on Powershell - OK
2. Try to Change GPO - Network List Manager Policy - to be available for changes from user  - NO success
3. Check - Local Policy on Server2 - too NO success
4. Try to change throught command  with PowerShell   ->   Set-NetConnectionProfile -InterfaceIndex 16 -NetworkCategory Public  Again - NO success
5.
 thru the registry:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles\
open the network profile that you have to change and modify the "Category" value:
0 = public
1 = private
2 = domain
NO Success
Did anybody have some other idea - what to do?
Thanks in advance.

Hi, the topology of th network ist the next:
ISP (DATACENTER) ->  SRV1 (phisical) +  SRV2 &SRV3 (virtual) 
Every one of them have 2 NIC  ( for server  2 and 3  - virtual  too)  
NIC1 - operates on private level -  192.168.1.1 dns, gate,dc (srv1)
NIC2 - real ip address, gate - gateway of ISP  dns - 192.168.1.1
When set up NIC1 - everything is ok .
NIC2 - action is : set ip and mask - enable without gate  - then it is in unidentified status  and  go in public state.
disable nic2, set up gateway  - and dns - 192.168.1.1  and again enable - everything is ok
But after restart  - nic2 - goes again in Domainauthenticated mode. :(
Additional:
On srv2 - i put RRAs role and smthing stange is that after enable rras service - all ports are shutted and machine pretendet to be invisible.
