Hi, I recently configured my Mac OS X 10.6.3 Server and now wanted to turn on Software Update Server too. When my clients, while being set to the correct IP address of the server, continued to say "No new update available." although they should see some, I opened the path to the 10.6 software catalogue in my browser: http://192.168.3.112:8088/index-leopard.merged-1.sucatalog There I found all URLs referncing files on the server to use a DNS name instead of the IP address 192.168.3.112 (at which the server actually is located). I don't have a local DNS server running in our network, however I had configured the one on this Mac OS X 10.6.3 server some time ago but turned it off recently. What can I do to make Software Update server use the IP address and not some DNS name that actually doesn't work. What could be misconfigured? Where is the place Software Update server looks for a DNS name to use instead of an IP address? Thanks in advance for all your ideas!
