Default NPT Server - NTP Client no sync

hi guys

since I got a secure area my linux servers don't not have internet connection at all...

so I've configured an NTP Linux server with this configuration but my NTP Linux Client are not sync the time with the NTP Server

Network: 192.168.3.0

1. I sync my NTP server to itselft
Code:
# ntpdate -du ntpserver
#service ntpd start
2. I syn my linux clients
Code:
# ntpdate -du ntpserver
ntp service for clients is stop

now my NTP server configuration

--------------------------------------------
Code:
# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery

# Permit all access over the loopback interface.  This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1
restrict -6 ::1

# Hosts on local network are less restricted.
restrict 192.168.3.0 mask 255.255.255.0 nomodify notrap

# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).

#broadcast 192.168.1.255 key 42         # broadcast server
broadcastclient                 # broadcast client
#broadcast 224.0.1.1 key 42             # multicast server
#multicastclient 224.0.1.1              # multicast client
#manycastserver 239.255.254.254         # manycast server
#manycastclient 239.255.254.254 key 42  # manycast client

# Undisciplined Local Clock. This is a fake driver intended for backup
# and when no outside source of synchronized time is available.
server  127.127.1.0     # local clock
fudge   127.127.1.0 stratum 10

# Drift file.  Put this in a directory which the daemon can write to.
# No symbolic links allowed, either, since the daemon updates the file
# by creating a temporary in the same directory and then rename()'ing
# it to the file.
driftfile /var/lib/ntp/drift

# Key file containing the keys and key identifiers used when operating
# with symmetric key cryptography.
keys /etc/ntp/keys
--------------------------------------------

when I run to sync my clients
Code:
#ntpdate -du ntpserver
results see the last line it says client is not sync by 87 secs...so what I have to do? which command so the time in my NTP client is the same as my NTP server?

Code:
13 Feb 15:19:14 ntpdate[7820]: ntpdate 4.2.2p1@1.1570-o Thu May 14 13:00:58 UTC 2009 (1)
