A common simple issue that sometimes pass by you while building a new server or virtual machine is noticing that the Network Card/Local Area Connection is not displaying domain.com Name but rather domain.com 1, 2…..etc (Check below picture).

It should be noted that the network adapter name is controlled by the Registry entry “ProfileName” value under
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionNetworkListProfiles.

The first network adapter profile name  when doing clean fresh installation should be “Domain Name” as in our example “Test.com”. If a new network adapter is created a new GUID registry key will get created in the above mentioned Registry location. This will be a new profile and will take the name “Domain.com 2”

It might happen especially on Virtual Machines to remove Network cards or install new drivers that remove Network cards and re-install them back which will create the new network profiles since the old registry key still exists.

In order to remove all these network profiles to get the default “Domain.com” profile you need to remove all these GUIDs from the Registry under profiles then disable your network adapter and Enable it again. It will come back with the default Domain.com.
