reverse DNS issue and NHD creation not working

Hi there, I am running a 10.4.6 on a PM G5. I have a recuring error in a few of my log files related to a DNS issue. The DNS is run by the central IT of the University here, so DNS is turn off in my server. What is different is the use of uppercase letter or not... Did anybody have ever seen such error... # system.log May 4 14:02:04 my-server servermgrd: servermgr_dns: gethostbyaddr() and reverse DNS name do not match (my-server.domain.uni-city.de != my-server.domain.UNI-City.DE), various services may not function properly - use changeip to repair and/or correct DNS # console.log May 4 14:02:04 my-server servermgrd: servermgr_dns: gethostbyaddr() and reverse DNS name do not match (my-server.domain.uni-city.de != my-server.domain.UNI-City.DE), various services may not function properly - use changeip to repair and/or correct DNS # acl.log [Time 2006.05.04 12:02:04 UTC] [Facility user] [Sender servermgrd] [PID -1] [Message servermgr_dns: gethostbyaddr() and reverse DNS name do not match (my-server.domain.uni-city.de != my-server.domain.UNI-City.DE), various services may not function properly - use changeip to repair and/or correct DNS] [Level 3] [UID -2] [GID -2] [Host my-server] But everything seem to work correctly with the DNS. I did check with the host and changeip commands: $ sudo changeip -checkhostname Password: Primary address = 123.123.111.66 Current HostName = my-server.domain.UNI-City.DE DNS HostName = my-server.domain.UNI-City.DE The names match. There is nothing to change. $ I also have a problem to create networked home directory (NHD). The button in WGM 'Create Home Now' doesn't work (nothing new here) and the command $ sudo createhomedir -a doesn't work also, nothing happen... Any idea? I know DNS is really important when running OD that why I make this dual subject post. The DNS issue is may be related to the NHD issue. David
