I’ve found something that appears to be a bug in the Windows 2003 GUI. I’ve had some trouble getting the status dialog box for the Network Connections to show. Selecting the LAN connection and double-clicking, right-clicking or File –> Status all failed. Usually I just go to the Start menu, select Network connections and double-click Local Area Network, but on some servers it just wouldn’t show the Status dialog. Same thing happened if I went through the Control Panel.
Since I’m writing this post of course I’ve found a workaround 
I could report it to Microsoft, but it would probably cost me big bucks to fix it…
Workaround:
Instead of just clicking Network Connections on the Start Menu (or Control Panel), right-click and select Open. The you should be able to get the Status dialog on your LAN Connections.
It worked for me, and might work for you too 
(Tested on Windows 2003 R2 SP2)
