MASSIVE OS X Server crashing! Please help me! SMB crashes and kills OSXS

Question

OSX Srvr 10.4.7 on a Mac Pro. I dont know what I did or missed versus every other server I've ever done, but I've got a major problem on my hands. Once a day my users have their access shut off, and i have to re-enable them. Every other morning, smb will crash so hard it kicks everyone off, then workgroup mgr won't respond anymore, and i have to hard power off the computer. This is running my company of roughly 23 users, and this replaced a Windows Server 2003. Not a good impression so far. I have logs I'm happy to post or email to anyone. They're huge, so I've obviously loused something up big time.
We're doing simple Windows file Sharing, Apple File Sharing, VPN, and eventually FTP. It's also running Kerio Mail Server. Someone please help me!
Here are some log examples to start with.

Hi Bill.
First please note:
"servermgr_dns: no name available via DNS for 192.168.200.250
Sep 20 17:54:21 Genesis1 servermgrd: servermgr_dns: no hostname set and unable to detect via DNS, services may not function properly - use changeip to repair"
Your first issue is you need to fix DNS.
Something needs to be providing forward and reverse DNS lookup for your OS X Server.
You might not have known this, but now you do: OS X Server -must- have working DNS. You don't need to run DNS on your OS X Server, but it needs working DNS.
DNS configuration is a bit beyond the scope of this reply, however.
In the meantime, edit /etc/hosts and do not touch any existing entries
but add the following line:
192.168.200.250 Genesis1
and kill -HUP lookupd. If you're not sure how, perhaps just restart the computer.
Next up, edit
/System/Library/LaunchDaemons/smbd.plist , adding the line in bold below:
<key>ProgramArguments</key>
<array>
<string>/usr/sbin/smbd</string>
<string>-F</string>
</array>
Of course, the text in the file itself should NOT be "bold" formatted
Be very sure to check the permissions on that file, and to leave them the same, or restore them if they change. It's really best to use nano/vi/emacs to edit the file, if you must use a GUI app, then go with TextWrangler or SubEthaEdit, both of which can be found at versiontracker.com
Let us know how it goes, and I'll send this to your email as well.
