When debugging an infrequent problem, you can't leave the machine in an unmanned environment (or go to sleep) if you need it to come back up after a crash. 2) Allow it to be disabled (can you do this?). #1 could be solved if you could disable it when you left the site. dennis ---------------------------------------------------------------------------- Emerging Technologies, Inc. http://www.etinc.com Synchronous Communications Cards and Routers For Discriminating Tastes. 56k to T1 and beyond.
