[Samba] How to I change server=[Samba 3.04.14a-2] to something else?

[AWC Lists]

So I have setup my samba box as a PDC and everything is working fine.  
There is one thing that keeps bugging me:
When I run locallly:  smbclient -L localhost -U%
I get the following:
-----------------------------
Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 3.0.14a-2]

       Sharename       Type      Comment
       ---------       ----      -------
       IPC$            IPC       IPC Service (ROI Fileserver)
       netlogon        Disk      Network Logon Service
       profiles        Disk      Profile Share
       office          Disk      Primary data share
       management      Disk      Data share for management only
       awc             Disk      AWC drivers storage
       apps            Disk      Application Files
       ADMIN$          IPC       IPC Service (ROI Fileserver)
Domain=[MYDOMAIN] OS=[Unix] Server=[Samba 3.0.14a-2]

       Server               Comment
       ---------            -------
       MYSERVER             My Fileserver
-------------------------------

So I have set the "Server string" to "My Fileserver", which shows up 
correctly in the comment.

I want to change the Server=[Samba 3.0.14a-2] being announced to 
something else.  I would like Server=[DataServer] as I do not want the 
server annoucing to the world it is running samba.  How would I do this?

I want to do this as when you browse shares in Windows XP its plunks 
"Samba 3.0.14a-2" into the task bar.

Thanks in advance.
