Hi, After substituting Ethernet NICs with new identical ones on a Windows Server 2008 R2 machine, new adapters were quite normally named "Local Area Connection <number>". If I try to rename them using the original adapter names (the ones I had given them when the original NICs were in place), using 'netsh interface set interface ... newname=...', the operation fails, most likely because the OS kept a memory of the previous adapters. Furthermore, the actual output of the netsh error is totally irrelevant, as it reads "You were not connected because a duplicate name exists on the network. If joining a domain, [...]". So, - Is there a way I can delete the previous adapters from HKLM and rename the new ones to my liking ? - perhaps submit the output message issue to the netsh team ?

Hi Lucas, Thanks for posting here. Based on my test, the previous adapters could be displayed in device managre MMC snap-in with set trigger “devmgr_show_nonpresent_devices”, please following the workaround below to check if it worked: · Run command prompt with administrator privilege. · perform “set devmgr_show_nonpresent_devices=1”. · perform “start devmgmt.msc” to start device manager MMC snap-in. · Click “Show hidden devices” on the View menu in Device Managers ,so that you should see the old devices that are not connected to the computer. · remove the old NIC form network adapters category. Here is an article for you refer: Device Manager does not display devices that are not connected to the Windows XP-based computer http://support.microsoft.com/kb/315539/en-us Thanks.

Hi, Sorry for the silence; the reason was that my question was in fact pertinent to a Server Core computer, which I didn't mention in my original post. I wanted to go looking for the answer on my own before posting back, but haven't gotten around to do it at this time. Thank you for the answer.Lucas Cohen MCSE, Windows Server 2003 - Security
