Is this a 64 bit OS?
The config.nt file is used only to configure the 16 bit subsystem. This system does not exist in a 64 bit OS. In 32 bit Windows you will find this file in the \windows\system32 folder. It does not exist in 64 bit Windows.Why do you need to access this file?
If your computer is running fine, then you should not worry. Just create a blank .txt file such as blank.txt and rename it to config.nt and put it in Windows\System32 directory for the love of it.
Using the same method, you can also create autoexec.nt file.
Please refer to http://support.microsoft.com/kb/324767 for a detailed explanation of how you should create the files ( for XP systems ).
