Hi, Gunter is correct, ${NETBIOSNAME} should be set to the hostname of 
your first DC i.e. the one that you provisioned.

Here is the proof:

 From ypServ30.ldif:

dn: CN=${NISDOMAIN},CN=mail,CN=ypServ30,CN=RpcServices,CN=System,${DOMAINDN}
objectClass: top
objectClass: msSFU30DomainInfo
msSFU30MasterServerName: ${NETBIOSNAME}
msSFU30OrderNumber: 10000
msSFU30Domains: ${NISDOMAIN}

 From my server (sanitized):

dn: 
CN=example,CN=mail,CN=ypServ30,CN=RpcServices,CN=System,DC=example,DC=com
objectClass: top
objectClass: msSFU30DomainInfo
msSFU30MasterServerName: DC1
msSFU30OrderNumber: 10000
msSFU30Domains: example
