SUS not update

I already install SUS Server. I can syncronize to
Internet, approve the list and enable update in group
policy. When look at client, i found that client's not
update even time is reach.

"Ricchie",

The first place to look would be your logs. What does the
SUS Server log tell you at the synchronization time?
There is a 20% variation in the total time, so that the
computers can pseudo-randomly patch their systems and
decrease the total bandwidth requirement. Otherwise, once
a certain time was reached, all machines would within a
few seconds start installing a needed patch and could
bottleneck the network.

Please check that log, and the log of the individual
Windows Update.log on a few of the client machines, and
reply back.
