Hidden network adaptors


I am about to set up NBL on 2 systems one of my systems is storing Hidden Network card settings which I cant find.

I have deleted my card from device manager, and from add remove programs. I have looked in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and I am unable to find any entries there relating to my Intel Pro Nic. I keep getting the error that the nic ip address is being used by another device that is not on the system.

On other point if anyone could help please?

One post I have read says i need to add this variable to the registry DEVMGR_SHOW_NONPRESENT_DEVICES this will enable me to see all devices that are no longer present.

Where should I add this - is it a new key dword string value?

sorry but I like to be clear when altering the registry.

Thank you

Open up device manager, but be sure to click Show hidden devices on the View menu in Device Managers before you can see devices that are not connected to the computer.

Hi thanks guys that worked but during the process I cant RDP in to this server anymore since i reinstalled the NIC, checked through everything seems ok RDP is still set up for administrators. any ideas Please?

Your help has saved me hundreds of hours of internet surfing.

Recheck your NIC settings to ensure they're correct.  Can youping it from the workstation you're accessing it from?

yeah can ping no problem can access the server in all ways it jus wont rdp in. I can VPN in from home it is just strange that RDP has gone.

Reboot the server and try again.

Already tried that one thanks still the same

Thank you guys I have split the points as both solutions actually dealt with the question I asked the RDP issue is a different matter would appreciate any ideas on that if anyone has any thoughts.

How to give NON administrators Terminal Service (Remote Administration)

This must be done on a server to server level, If you require a lot of users create a GROUP called TSRemoteUsers in active directory and add your users into the group, then carry out the steps below. Ill assume we are only dealing with a couple of users.

Ill also assume you have Terminal Services (Administration Mode) installed and running on the server, if not open control panel >add remove Programs >windows components >Terminal Services, When Prompted ENSURE "Remote Administration" is selected.

1. Using an admin account open a remote admin session to the server in question.
2. Click Start >Programs >Administrative Tools >Terminal Services Configuration
3. Click Connections
4. In the right hand pane RIGHT CLICK the RDP-TCP connector and select properties
5. On the permissions tab click "ADD"
6. Add your user/group in here and select the appropriate level of access.

If it aint working ensure you not in application mode (Unless you have to be!!)
