I am trying to install windows 7 to a notebook via the network boot PXE method. Everything seems to be going ok expect when i go to enter my password to get into the machine to copy the files. Look at this article, this is what i followed:

http://blog.ryantadams.com/2008/02/01/how-to-boot-from-the-network-pxe-boot-with-tftp-and-windows-pe/

It works until i enter: net use y: \\192.168.1.5\cd
and i get a line that say's : the password is invalid for \\192.168.1.5\cd  (followed immediately by a prompt that says)
Enter the user name for '192.168.1.5':  ( i do this and next comes the password option)
Enter the password for '192.168.1.5:

At this point the keyboard no longer works, i cannot hit any buttons on the keyboard besides enter, and when i do, this is the error message i get:

The user context supplied is invalid
