cmd.exe changes in MS Vista

I have noticed several changes when using the cmd.exe prompt window.

First when I try a ipconfig /renew and when try netstat -bv

Both commands failed with same error message:
The requested operation requires elevation

I am logged as administrator in the console, i.e is a laptop in a workgroup, not conected to a Domain, a stand-alone machine.

Anyone have a lead or link where i can get updates of the command prompt in Vista? I tried Technet and got none...

Thanks
