Can't access properties of a network interface card

I have a Dell M90 laptop with a NetXtreme 57xx gigabit network controller.  The card seems to be operating properly.  It gets a dhcp address without a problem and connects to the network.  The problem is when I go into control panel under network connections, right click on the NIC and try to go to properties.  When I do this, I get the message "an unexpected error has occured".  I also get this same message for the wireless card.  The device manager shows both cards operating properly.  I have uninstalled the drivers and reinstalled with new drivers from Dell's website.  The problem also exists in safe mode.  The hardware will pass the diagnostic program from Dell.  I have tried to log on as a new user so a new profile is created and still have the same problem.  I am out of ideas.  Thank you.

To work around this problem, reregister the Netshell.dll file. To do so, follow these steps:
Click Start, and then click Run.
In the Open box, type regsvr32 %systemroot%\system32\netshell.dll, and then click OK.
In the RegSvr32 dialog box, click OK.
Test to see if you can open the properties of the network connection in the Network Connections folder.

If the issue is resolved, you do not have to follow the remaining steps in this article. If the issue persists, and you receive the error message that is mentioned in the Symptoms section of this article, follow these steps:
Click Start, and then click Run.
In the Open box, type regsvr32 %systemroot%\system32\ole32.dll, and then click OK.
In the RegSvr32 dialog box, click OK.
Restart the computer.

chuchyyy, just a word of advice. EE doesnt take kindly to copying materials from a website, without proper credit (eg a link) to the source, as most of the material, esp from Microsoft is copyrighted.....

Just want you to be aware.....

I tried to reregister the Netshell.dll as suggested above.  It gave me the message it succeeded but I still had the same problem.  I then reregistered the ole32.dll, restarted the system and now it will let me into the network card properties.    I will let the user do some testing but for now, it looks like it is fixed.  Thank you for your help.
