Can you provide some information ?
1. How many systems are managed in your network ?
2. How many systems are not taking update ? Difference between dat version in EPO and these managed system ?
3. When you run agent wake-up call to those systems, is it completing properly ?

The first place to start looking is on the client machine itself - the logs you're particularly interested in are the agent log (called agent_<name of machine>.log, and the mcscript.log.
Check the agent log first to make sure that the update task is being invoked correctly - if it is, but is showing an error, more detail about the task itself is in the mcscript.log.
