reset qsecofr password?

[dcharmatt@xxxxxxxxxxxxx]

We recently purchased a little backup 170.  The problem is that we are not 
able to sign on under qsecofr or into dst.  The previous owners of this 
machine apparently do not know the passwords either. After trying to sign 
on using various default  passwords, the console disconnects and the 
machine gives us an error code of A9003C60.  Is there anyway to reset the 
qsecofr or dst passwords without having to do a fresh install?  The 
machine is running on v4r5. 


TIA,
