Hi Edward,<br />
<br />
I've come across this problem in the past, but there are several possibilities that can cause this to happen and answering the following questions will help narrow down the field. <br />
<br />

<ol type="1">
<li>Are you able to open the properties of other hardware items on that same machine? </li>
<li>Have you tried going accessing the NIC's properties from both the Device Manager and from Control Panel\Network and Internet\Network Connections?</li>
<li>Tried uninstalling and reinstalling the NIC and drivers?</li>
<li>What level is UAC set at? Tried temporarily turning off UAC on the problematic machine?</li>
</ol>
<br />
Try the above but there are too many possibilities to list them all depending on circumstances. Please provide more info. A screenshot of where you are striking the ghosted properties button could also be helpful.<br />
<br />
Thanks...

On most machines in my environment I would be prompted for admin ID and Password if required when I need to open something that requires it. In this case on this machine I cannot get to the properties of the LAN adapter. I ran network and sharing as admin and still no luck. Anything else I can try?

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages.
