Uninstall the network card driver and software reboot server.

Reset the TCP\IP stack

Are you pointing the system to the drivers or are you allowing the system to search for the drivers? Have you tried not going through device manager instead install drivers from the driver installer>

this worked for me:
HKLM\SYSTEM\CurrentControlSet\Network - delete the "config" key and all is well in the world. 2 1/2 hours with one Dell rep. call back 5 minutes with another. amazing.

#dariusg - tried both ways

Sorry boys no points on this one. thank you though

The TCP\IP reset should have taken care of  that. I'm glad it is working

You should have read my article:

Click Start, click Run, type regedit, and then press ENTER.
Locate and then click the following registry subkey:
HKEY_LOCAL-MACHINE\SYSTEM\CurrentControlSet\Control\Network
Right-click this subkey, click Export, and then save the selected branch in a file.
Click the Network subkey again, and then delete the Config entry. Do not delete the Network subkey. The Config entry will be reconstructed when you restart the computer.
Restart the computer. You may have to manually turn off the computer.
