There was a thread on this issue 6 months ago. Based on the information I took the
following steps to harden my NT RealSecure Engines. They have be running in this
configuration for about 5 months. I think the most important step in hardening the
workstation was NOT intsalling the NT Network. RealSecure and the Consol works fine
without being part of the network. I am willing to walk to the computer room when I
need to work with the engines.
