[Samba] Can't login into PDC, Running Samba 2.2.7 on Suse 8.2

[Adam Foreman]

I am new to Linux and Samba, and I have attempted to set-up a Samba PDC.
However, every time I try to log in to my domain using Win XP or Y2K I
receive errors. Please keep in mind this is my first time doing this.
 
Steps Taken:
-Setup the samba configuration (smb.conf) using swat. [SEE BELOW]
-Created User Linux accounts, (default group:100, shell:/bin/false),
using YaST2.
-Created User Samba accounts, (smbpasswd -a "username")
-Created Machine Linux accounts, (/usr/sbin/useradd -g 100 -d /dev/null
-c "machine nickname" -s /bin/false machine_name$)
-Created Machine Samba accounts, (smbpasswd -a -m "machine_name")
-Added root to smbpasswd, (smbpasswd -a root)
-Ran testparm, results: OK
-Ran smbclient, and was able to login locally and remotely via ssh.
-Pinged server.
-Configured TCP/IP properties for DHCP, configured WINS to "Server IP". 
 
Final Result:
Able to add the machines to the domain, able to browse home directories
however, not able to create folders or add files. HOWEVER, HERE'S THE
KICKER, AFTER I RESTART THE WORKSTATIONS AS INSTRUCTED BY WINDOWS, I
CANNOT LOGIN INTO THE DOMAIN. I get 2 separate error messages for XP and
Y2K and I can only log in to the workstation locally.
 
WinXP Error:
The system cannot log you on because the domain POLC is not available.
WinY2K Error: The system cannot log you on to this domain because the
system's computer account in its primary domain is missing or the
password on that account is incorrect.
 
Checked log.smbd and found the following.

  end of file from client
 
I used a valid account so is the machine account causing this error? Did
I not setup my machine accounts properly?
