I am having some registry problems and I would like to get a good tool that repairs, cleans and maintains the registry. It has to work on Win2K Server and not require reboots. There are so many choices out there, I don't know which ones are good or not. I need a highly professional one that will not cause any additional headaches for me. Our servers require 24x7 uptime, so I need one that will accomodate that. Any suggestions?
