The DNS Server service should listen on DNS port 53, but that port is owned by the process.

Any Idea what this means and how you resolve it. It gets displayed in SBS 2008 when you run the Best Practices Analizer and in SBS 2008 console.

I noticed companyweb is not opening properly. In that period I changed IP of server and DNS a name and ptr record were not changed. I fixed manually thoose records from old IP to new IP. Issue is still here after those changes. Note this is new installation os SBS 2008.

Thank you in advance

Try doing windows update and see how.
Update to latest service packs on this server and the the Fix My Network wizard in SBS console may eliminate some of these issues

with an elevated access on widows 2008 ( run as )  open a command prompt and  do   "netstat -ab"
that will list all listening processes with their open ports . identify the port open as 53 and which process is using it , then eliminate the process if not used .
after eliminating the process either reboot server or restart dns service .
Good luck
Sounds like you are trying to start the DNS service on the default port 53, but some other process is already running on port 53. Could be an alternate DNS Service.

Start > Run > cmd

c:\> netstat -nabo | find ":53"
grab the PID XXXX from there.

c:\> tasklist | find "XXXX" (the PID).

kill that pid, or find the corresponding service and stop it / disable it / uninstall it. (start > run > services.msc)

Hi guys
Thank you for advice. Unfortunately none of answers gave right answer but it did help troubleshooting.
port 53 was owned and run by dns.exe. On DNS server settings I notices that settings changed after changing IP address of the server. Server didn't allow accepting DNS requests over new IP. That was one check button and everything worked again perfectly.
