Get windows user name with form authentication

Hi
 
I am using form authentication and I need to get the windows login name.  How can I achieve this ?  I have tried
 
strName = Principal.WindowsIdentity.GetCurrent.Name

strName = User.Identity.Name

but it does not work, can anyone enlighten me ?  Thanks in advance.

Best regards

SST
