I used the following tutorial to install ISPConfig3 on Debian Lenny with the necessary services. http://www.howtoforge.com/perfect-server-debian-lenny-ispconfig3 I have run into the situation a few times that DNS resolution will fail. After a few occurences, I noticed that the service fails to start upon rebooting the machine. Therefore, it takes a manual action to start the service which rectifies the problem. I could easily be user error on my part when creating the init.d scripts. My other theory is that perhaps MyDNS is trying to start before MySQL is up and running which causes a failure. I do not have much experience with startup scripts. How can I troubleshoot this problem?
