Try this trick from a previous ntsysadmin post. I bet you have a phantom nic on that DC.
<snip> I never heard of this before, and just read it on the NT Sys Admin news feed. …To work around this behavior and display phantom devices when you use the Show hidden devices command: Click Start, click Run, type cmd.exe, and then press ENTER. Type set devmgr_show_nonpresent_devices=1, and then press ENTER. Type Start DEVMGMT.MSC, and then press ENTER. Click View, and then click Show Hidden Devices. Expand the Network Adapters tree. Right-click the dimmed network adapter, and then click Uninstall. Definitely going into my bag o’ tricks. <snip> Doug Hilderbrand | Systems Analyst, Information Technology | Crane Aerospace & Electronics -----Original Message----- From: Kurt Buff [mailto:[email protected]] Sent: Tuesday, November 16, 2010 4:49 PM To: NT System Admin Issues Subject: Re: A real puzzler...
