title: Ad hoc updates to system catalogs are not allowed
body: <p>So I'm trying to manually update hash for one user. I tried updating view, as tables are not visible. </p>
  
  <p>I tried starting in single user mode, changing "sp_configure 'Allow updates',1", and so on, with no luck.</p>
  
  <p>Is there any way. I don't know passwords, just hashes, as updating from 2000 SP4 to 2008 R2 failed, and I need to have credentials on 2008 R2, just like on old 2000.</p>
