System error 2 has occurred?

So I was working on this client and couldn't seem to use net.exe
The file was missing!  So this was easy to fix, I got my 2003 install cd, and typed the following
expand -r cdromDrive:\i386\net.* %windir%\system32
should be two files.

So typed net again, and got:
System error 2 has occurred.
The system cannot find the file specified

if I typed net use, the commands worked fine.  Odd...

So after a little digging, I found that net.exe needs net1.exe also.  The solution was :

expand -r cdromDrive:\i386\net1.* %windir%\system32

And viola, everything hunky dory.
