I have a NT Workstation 4.0 (SP6A) that seemed as if it was locked up when I attempted to log in as Administrator. The machine is a firewall and stays on all the time. After a reboot, the system will not allow me to the desktop by stating "unable to log in because netlogon service is not running on this machine." Most of the research says to apply the latest service pack. That would be great if I could get to the desktop, and it already has 6a on it. Any tricks or ideas would be appreciated. I hate to have to reload the OS because the firewall software I am using is such a pain to reapply. Thanks in advance.
