Fedora Networking :: Can't Stop Named Service

I am new in configuring named.I want to set my firewall (Fedora 11) as a name server. The local domain is a Windows domain. I'd like internal users translate domain name into IP on this server when they go to the internet. After reading some posts on the web, I set up named as below. It seems the named does the job but with some problems.

1) When I start the server, I couldn't find the named process even if the file "named" is in /etc/init.d. I can browse Internet on the server with domain name (DNS works locally). But internal users couldn't get the domain name translated. If I shutdown the server at this stage, it will shutdown within 1 minute.

2) If I run "service named start" after the server boot up, I see process "named" and named work okay. Both internal user and local host can browse Internet with domain name. However, any command starting with "service named" has no response after this, such as "service named status" or "service named stop". I can see it shows "stopping named" and this last forever. I have to kill the process then restart named server so that named may run again.

3) If I shutdown the server now, it will take 4-5 minute instead of 1 minute in 1). The shutdown stuck at "shutdown named" for 4 minutes. Even if I kill process named before the shutdown, it will take 4-5 minutes.

It took me a week on this issue. I appreciate if you could take a look my configure files and guide me through this.
