UNEXPECTED SHUTDOWN

I am new to Server 20003. For second time, I have reinstalled from scratch the Server 2003 OS (SBS Premium 2003). The Server is a HP Proliant ML 370, dual processor XEON 2.8 gz, with a 72 GB SCCSI drive.
This second time, searching the event log, there is a warning related to ‘dynamic registration or deletion of one or more DNS records associated with DNS domain….’

I think I have a wrong configuration, but I need clues to solve this matter.

Thank you,
Miguel Torres
