Dear All, I am encountering a major problem in my "Windows NT Server Version 4" "It restarts and boots when logon screen comes". I tried to start the system again but no use. As soon as the log-on scree comes (Ctrl-Alt-Del Screen), the systems restarts itself. Can any body explain where is the problem and How can this problem be solved ? Thanks in advance. Rohit
