I understand you are using WolfPaw to host your mud right?
From memory, these guys run some system which hardens the operating system (I think it is called PitBull, but was a long time ago since I looked at the problem). Unfortunately some of the operating system hardening breaks the interprocess communication which Dawn uses for DNS lookups and Hotreboots. Specifically file descriptors need to be inherited by the child process after forking.
I believe the hardening system they use may be able to be customised in order to get hotreboot and dns resolution working... but it will most likely depend on your hosting company to provide you will instructions on how to enable support for this functionality. If they don't I suggest finding a new hosting company.
