Rick,
The problem seems to be that your autoexec.nt file is either corrupt or missing. We have been running into this problem where I work. What we do is replace the file in the Windows/System32 folder.
Change the attributes to Read Only and Hidden.
To do that, after you replace the file, right click on it, go to properties, and under the General Tab, place check marks in those fields. You may have to change your folder options to view hidden files if you haven't already.
To do that, open up My Computer, Click on Tools, and then click on the View tab. Scroll down and you will see an option that says Show hidden files and folders. Enable this option. You will get a warning, but tell it ok. Hope this helps, and seems to work on my end.
If you can't find the file using
JoeD's method, e mail me and I will be happy to send you one.
