All my machines except one are windows 2000 professional machines.  The 
other is winme(for my daughter's older games).  I think i managed to 
screw up my BIND configs though.  erasing and reinstalling Bind is not 
fixing it.  What files does everyone want posted so this issue can get 
fixed?

I could easily just reload the system..but that's the winders way of 
doing things..:)

My "Foundation" verse:
Isa 54:17  No weapon that is formed against thee shall prosper; and 
every tongue that shall rise against thee in judgment thou shalt 
condemn. This is the heritage of the servants of the LORD, and their 
righteousness is of me, saith the LORD.
