I have a machine on our office network running windows NT Workstation 4.0 SP6 also running Novel Client 4.6 sp2. The problem I'm am having is this machine has all of a sudden (been working fine previously) started to reboot it self automaticly, I originally thought it was sometine in our lotus notes program that was doing it but it does it without Notes running also. There seems to be no common denominator does it while working in Office programs, using windows explorer, or sometimes just logging in. Any help or I deas would be appreciated, I have not reloaded NT yet but im leaning towards that.
