Proves more difficult than I imagined. I don't know what I should modify.

I already did some dumps, but I don't know what to look for, or in what 
file. Those dumps are strangely formatted.
I could use "ldbedit -e nano -H group_mapping.ldb" : I see several 
occurences of that 65533, but I don't know the context, so I don't know 
if I can modify it or not.

A few weeks back I rejected the idea of just starting from scratch. I 
don't have that many users/PC's, but I'm afraid some services running on 
a Windows-server will need re-installation, and I can't do that anymore.
Maybe I should just try with a copy of the virtual machine.

Anyway, Rowland, I very much appreciate your effort. I'll try your other 
suggestion about deleting some lines in the sam.ldb and run the 
sysvolreset. But where do I stand then ? Should I be able to join 
workstations then ?
