Win2000 AD & Kerberos configuration?

[drew.arthur at mail.sprint.com]

I am trying to configure Samba 3.0 Alpha 17 to join an existing AD 
Domain. 
How do you find out what the Win2000 KDC realm name is? Is it just the 
netbios name of the server?
 
In the krb5.conf file the ADS-Howto documentation says you must add the 
following:
[realms]
YOUR.KERBEROS.REALM =  { 
   kdc = your.kerberos.server
}
 
If my server name is sssmqs, would the kerberos REALM name be 
SSSMQS.KERBEROS.REALM?
